I'll be honest, last two systems I've built have had Kensington ValueRam in
them and they've run great. Never heard about any problems with OCZ though,
everyhing I've heard about them is that they're primo stuff.
If you're looking for perfomance go with OCZ, Mushkin, or Corsair, if you're
going for price or stability, just about any reputable company (Kingston,
Crucial, Viking, OCZ, Mushkin, Corsair) should be fine.
