i've read several posts about RAM and how you should DIY to save money instead of having apple do it. my plan is to end up with 1.5mb in my new imac (512 stock and 1gig added myself). crucial has a 1gig stick for $184.00. is this a competitive price for 1gig of ram? i read in a previous post that they've seen it for around $100, but i've yet to see any for that price...maybe i'm looking in the wrong place so far.
