Whatever is going at the right price and works at the speed I want. I buy the cheapest, check it out and if it doesn't hold up I exchange. Nice and simple. Kingston are fine, but my friend paid three times what I did for an identical stick (aside from Kingston rebranding). Same deal, for the most part with Crucial et al. as far as I can tell. Personally never had any real trouble, even with Winbond and the like. In fact I can't remember the last time I had memory fail me. I did have to exchange a stick of 512Mb DDR 400 when it was pretty much "the new thing" because it would not work a CL2 with the rest of the timings I wanted. But that was a painless exchange for a stick made by the same brand as the other 512Mb DDR 400 stick I had in the same system. So aside from a little time and some diesel, nothing was lost.
