Actually there is going to be several new models out that you can look into. IMFT has their 25nm flash out, so there is drives starting to pop up that use it. These drives will have better cost per gigabyte since they use less silicon. Intel 320 series should have some decent specs. http://www.pcper.com/article.php?aid=1102
Also, I believe Corsair has a SF-1222 drive with 25nm flash out. Can't remember where I read the review for that.
