. I purchased one several months ago for a bit less and it's great. However
, the warranty period is shorter than for a new model.
The best price I could find for the monitor new is $190 shipped from Tiger
Direct:

and Buy.com:
http://www.buy.com/pr/product.aspx?sku=222292988&sellerid=20830
. That's a good deal, if the monitor's specs fit your needs well. These
used to sell everywhere for over $300. Sears, for instance, has it priced at
$390. Office Depot wants $370. Newegg is selling it for $359.
Buying the monitor new will likely get it to you quicker. It takes a bit of
waiting sometimes to get a refurb from BenQ.
There are also other refurbished monitors BenQ:

, including the 27" version of this monitor ($300, EW2730) and TN-based
designs.
A-MVA panels have, along with C-PVA, the highest real contrast ratio of any
LCD monitor. Unlike C-PVA, A-MVA computer monitor panels aren't known to
have any significant issue with black crush. You'll see a lot of big numbers
in monitor specs for "dynamic" contrast, but those should pretty much be
ignored for computer monitors. Real contrast is what counts. IPS, which has
some positive qualities, like color consistency, generally has dramatically
worse real contrast than these A-MVA panels.
This monitor has true 8-bit color processing, unlike e-IPS and TN monitors
that use 6-bit color with 2 bits of dithering. True 8-bit color has less of
an issue with noise from the dithering. High-end panels use true 10-bit
color. Also, this panel has a standard gamut white LED backlight, which is
suitable for the sRGB color space. It does not display wide gamut content,
like the AdobeRGB color space. Most consumer panels are sRGB.
The monitor has a semi-gloss display surface, in between matte and glossy.
Reflections, as with glossy panels, could be an issue if you have light
shining onto the panel or have high ambient lighting. However, having less
interference from anti-glare surfacing makes for a cleaner-looking image --
if you can avoid reflections from lighting. Matte displays are generally
better for high ambient lighting situations, or for when light is shining
onto the panel.
High contrast panels make text easier to read because the difference between
dark and light is stronger, even at lower brightness levels. They also add
a sense of realism to imagery by washing out the visuals less.
It can be VESA mounted, and the stand tilts but is rather short and does not
pivot to portrait mode. It has two HDMI ports (supporting DRM), DVI, and
VGA. There is also a built-in USB hub.
The A-MVA technology has one significant drawback for some users, and that's
pixel speed. I play Star Trek Online and slower games like SimCity and
Civilization IV with it and have no trouble, but high-speed gamers should
choose a faster panel. It's fast enough for video playback, in my opinion.
However, if you watch a lot of high-speed video, like skateboard
competitions or something, you may want to look into a faster panel.
A-MVA is being improved to have 120 Hz and those faster panels will be on
the market fairly soon, hence the price drop for these units that use the
older slower tech. However, don't expect them to sell for this price, at
least not for a long time. 120 Hz A-MVA panels, though, should finally take
care of the slow speed issue for most gamers, although professional FPS
players will still likely want 120 Hz or faster TN for the fastest possible
speed.
This monitor, like most consumer-grade panels (unlike a mid-high end Eizo,
for instance), benefits quite a bit from calibration.
The biggest competition is from e-IPS. Those monitors use 6-bit color and
have inferior contrast. They tend to have faster pixel response, a stronger
anti-glare coating, and tend to be offered in 23" rather than 24". Both A-
MVA and e-IPS tend to be a significant step up from TN panel technology,
unless a user needs the fastest possible pixel response. It's now possible
to find an e-IPS monitor in this price range. Personally, I prefer the
improved contrast of A-MVA. In comparison with H-IPS and S-IPS, which are
higher-grade IPS panel types, e-IPS' viewing angles are not as wide.
TN technology's big drawback is that it has very narrow viewing angles, so
colors and gamma change. TN, especially in large monitors, is generally not
great for simultaneous usage by multiple people (such as watching a video as
a group) and color-sensitive graphics/photo editing. However, there are
grades of TN panel, and the technology is the fastest in terms of response,
which makes it, especially when paired with 120 Hz refresh, the best choice
for single usage high-speed gaming. Not all TN panels are fast. Some lack
aggressive overdrive circuitry, just as some IPS monitors are slow --
usually monitors designed for business use.
