Hello folks, I'm new. As in completely new. I just purchased my very first Mac. I think I got a pretty good deal and I'm going to pick it up in person so hopefully I'll be able to check it out and see if it's all that the seller says it is. There's a link to it below if anyone wants to check it out.( sorry about the long link ). One thing I need is a power supply. I've read that Apple brand ones are really not very well made. Any advice on an alternative? Any general or specific advice will be sincerely appreciated. Looking forward to learning, Thanks, Dave http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&ih=015&sspagename=STRK%3AMEWN%3AIT&viewitem=&item=250071329240&rd=1&rd=1
