I'm thinking about purchasing some PNY RAM (Fry's has 8 GB on sale for $35). I was wondering what sort of quality we're talking about here. MacMall also has some Kingston 4GB sticks on sale for $29 each, which would be entirely worth it if PNY has quality issues. I'm running into mixed reviews in other places, so was wondering what the experience of MacRumors users has been. I know Kingston has a great reputation, so I don't need to know much about that (unless you've got any advice on how PNY stacks up against it!). Thanks!
