Thank you all for your comments and suggestions. I ordered a replacement power supply this afternoon. $249 delivered. Used. 90-day warranty. Reasoning: A new machine will not support OSX 3.9 which is mission-critical as I do not want to replace or upgrade Adobe Creative Suite 2. And, I love the machine. It has been wonderful, and very, very reliable. It's a dual boot FW 400 model, packed with RAM with a Vortex fan on the CPU. I took a chance on a used power supply; probably not the brightest thing to do, but <hardcoremac> tests them to make sure they are strong. He said he's never had one come back during warranty. The alternative was spending an additional $100 for a refurbished unit, with a 90-day warranty. "Ya pays yer money, and ya takes yer chances." Thanks again for your perspectives. Members of this list have been very helpful over the years! Interesting to read too. I'm no expert or technician, just a mac user whose first machine was an SE. :-) Cheers! jonny /// >jonny, > >If you decide to upgrade, I am interested in your dead MDD. > >Rich > >On Mar 17, 2010, at 1:54 PM, Bruce Ryan Nakamura wrote: > >>Hello, >> >>There are several sellers on Ebay who sell with a warranty.
