Hello Laura - we're in the same boat, and while looking around I found out that the CPU upgrades are increasingly getting hard to find. As far as the problems go, the only one I recall is the sleep problem with the Powerlogix upgrades, but I don't know if that one is still current. For all my shopping I turn to OWC www.macsales.com, but right now www.yourmacstore.com has Giga Designs upgrade on offer for $300: http://www.yourmacstore.com/shop/shopexd.asp?id=483 Hope it helps.
