I'm about to pull my RAM trigger (2x1GB), but can't quite decide if I should go with Crucial or OWC. Is the extra $30-40 that Crucial charges worth it? I hear Crucial modules are essentially identical to the one's Apple puts in; I've come across more reports of issues with OWC RAM, though they seem to be good about replacing it. What is the difference between the Apple Certified (Netlist) and Apple Qualified (OWC) that OWC sells? The less expensive Qualified sticks look more like the ones from Apple. Finally, with memory prices dropping, has anyone tested these guys' 30-day MBG to get the difference in price? Personally, if they refused to give me the difference back, I'd just return the RAM and buy another set at a lower price (assuming it's not something trivial, like $5 or $10). I'm hoping, though, the these guys will play nice and I won't have to do this.
