Looks like nobody will have these for cheap for a while. I read somewhere that there was a 'crunch' of sorts on 15" LCD's, which is driving the prices back up. 17" LCD's are still the best buy.
But back to the subject, do a pricegrabber search for 15" lcd's. There's a Phillips black 15" for $199 that'll be fine for non-gaming, general usage (25ms avg. refresh).

Oh, and Staples has a few under $300 if you do a search on their site, add their recent $30 off $150 coupon posted elsewhere here on T-mo

and the price becomes quite acceptable and close to your budget (free shipping from Staples, too). Good luck.
