I'm looking for 6 8580/6582s to fill up my MB-6582 to the brim. It would be preferable for the seller to be in the US, but I'll look over it if the price is right. I'm hoping to spend around 200$ for them, going higher is going to be hard to negotiate with my wife ;) These chips are starting to get really hard to find, so even if I can only buy 2 or 4 from someone that would be great. ~Chris
