Another quality brand worth consideration is Compucase/Heroichi, they're OEM for some antecs. Channelwell also makes good stuff, and has also been sold under the Antec, Nspire and other monikers, too.
The 0735 abd 0730 Enhance units are very good, but I'm not a fan of their 1125 line. they have smallish heatsinks and noisy fans to make up the difference.
The likelihood of your actually needing anything over 350w is really small.....
Two of the better deals from pricewatch include the 350w Heroichi from newegg for $44, free shipping, and the 350w Sparkle from Directron for $45, shipped....
