I just wanted to say thanks to Gavin at Mac Upgrades for a really great job.
If you've got a Mac that isn't old enough to give to the kids but is starting to act up you could do a lot worse than give these chaps a call. They will upgrade just about anything with anything and they keep a large stock of second-hand parts which could save you an expensive trip to Cuppertino.
They've just mended a powermac, upgraded my production powerbook and replaced the monitor strip in Nick's iBook. The work was done quickly and the price is very reasonable, I can't recommend them highly enough:-)
Finally, I you do head up there with a bootful of old kit, can I suggest the cooked breakfast at the World Famous Comfort Café Fourwentways, Little Abington, Cambridge, CB1 6AP (tel 01223 837 891)
