Just about to get a MacPro. Apple (UK) are offering refurb 2.66 standard spec machines for £200 off. Is this a good idea or not worth the savings in the long run. I've been a Mac user since '91 so a little bit of fiddling (HD replacments/OS reinstall/RAM upgrades etc) are not beyond me, but other more major problems are a little more scary and I want this machine to last 3 years. Currently using an ex demo 17" Powerbook which has been trouble free.
