X-25M. It's not the latest and greatest, but I got it for $170 after a sale and mail-in rebate.
If you've got more cash to spend, you may want to look at the new 310, or 510. There are other great SSD makers, but I chose Intel based on the price and general high reviews.
Wow, that's apparently a great deal on the X-25M--they were retailing for $220 at NewEgg.
I'm waiting to see what comes out in the next few months, as apparently OCZ and Intel are building drives with the new SandForce chipset. Don't know if the improvements will be significant, though...
