I bought an innexpensive stick of it to toss into my little old Celeron. I got a 64MB 100MHz FSB DIMM from them and it's worked perfectly fine.
Then again, the system itself is only a 66MHz FSB. So it could be that it's crappy as all hell and I just don't know it because it's so far underclocked.
If you're going for the latest-and-greatest, I'd suggest don't take chances. Stick with the best. It'll cost more, but stability is worth it's weight in platinum.
If you're just going for upgrading an old system to keep it from becoming a door stop, then go with whatever you dare spend so little on.
I believe the proper phrase for today is, "You get what you pay for."
