The Best

Whats the best ssd on the market for under $200 good enought for windows 7 home premium 64bit???

The best deal changes daily, but you are looking at 120-128gb in that price range. There is a pretty good deal on the Crucial M4 at Newegg for $165 FS. You need to update the firmware to take care of the 5200 hour bug, but Crucial drives are quite reliable, see THIS.

a couple of days ago the samsung 830 128gb drive was on sale for $179 at tigerdirect, it consistently outperforms the crucial m4. but, with the promo code newegg is offering (and if you don't have to pay sales tax) the m4 is by far the best deal. very reliable drives, they don't use the sandforce controller which has plagued users, and they offer great speeds in real world performance.
