Sounds like Gaz you have been real unlucky, I bought from Time in 1997 a pentium 2 PC and it still works fine, not a thing ever went wrong with it. So I was after getting a new machine with a bit more power, I've always been on the lookout for good deals and when I saw the Time mirage 2600+ 512MB 120gig with a radeon 9500 all for £899.99, I thought sounds great and bought one for christms and so far so good , runs like a dream. Dunno how I ever stuck with my old machine so long, I'm well impressed with XP, makes everything so easy to perform commands. I got a vision master iiyama 19 inch monitor from the excellent scan.co.uk and some decent speakers and the whole thing looks and sounds great.
I have heard people say stay away from Time machines and I think thats abit unfair with most things only ever hear about the unlucky few that may of had a faulty machine and never hear much of the satisfied customer. Anyway all I'm saying is I would recommend Time for a great deal and a great PC.
