I found these while seaching for some drives for my 2 5700's. I think they are mispriced since if you search for the same model number it comes back with 2 hits, one for $49 and one for $97. I also used a coupon "sale15" to get an additional 15% off with free shipping. Then if you use google checkout you can get an additional $10 off your order.
So 2-4gb SSD SLC Flash drives for $73.30 shipped
The specs look pretty decent...
