Update:Unfortunately, this deal is sold out now.
Nothing beats a big monitor. (Well, maybe two big monitors.) If you're still plodding along with an old 17-incher or the like, it's high time for an upgrade.
TigerDirect has the AOC 2330V 23-inch LCD monitor for $129.99, plus around $9 for shipping. This is a new unit, not a refurb, and you don't have to mess with any rebates. I've seen 22-inch monitors this low, but never a 23-incher.
The 2330V offers full 1080p resolution (i.e. 1,920 x 1,080), and its DVI input supports HDCP--meaning it's suitable for showing Blu-ray movies if you happen to have a Blu-ray drive in your PC. (There's also a VGA input if you're kicking it old-school.)
Other specs include a 30,000:1 contrast ratio, 5ms response time, and a three-year warranty. That probably helps explain why the monitor has an average customer rating of 4.6 stars (out of 5) from nearly 100 TigerDirect customers.
One tiny shortcoming: the 2330V comes with a VGA cable only. If you're planning a DVI connection, you should be able to pick up a cable cheap from someplace like Meritline or Monoprice.
Bonus deal: Walmart has a Lexmark Z2420 wireless inkjet printer for $39 (plus sales tax in most states and 97 cents for shipping). That's a mighty sweet offer on a dual-cartridge printer that does the Wi-Fi thing. Around 275 shoppers rated it just over four stars. The warranty's only 90 days, though--what's that about, Lexmark?
