Score! Buy.com has a 22-inch wide-screen LCD monitor for the lowest price I've ever seen: $149.99 shipped (after a $20 mail-in rebate). And it's new, not a refurb. Score!
OK, settle down; there are a few caveats. First, I rounded up a bit. This is actually a 21.6-inch LCD, though I don't think anyone's going to quibble over four-tenths of an inch. Second, the Optiquest Q2162wb is a decidedly entry-level monitor. Although it offers a native resolution of 1,680x1,050 and a 5ms response time, it has only a VGA input--no DVI or HDMI. No speakers, either.
If you can live with that, you should find this to be a fine monitor: 20-odd Buy.com buyers rated it four stars out of five. The rebate deal (PDF) expires November 30, so you've got time to mull it over--though I don't expect these will last long.
