Huw,
Don't know if Time have improved, but they used to be the biggest heap of shite around. Consequently I wouldn't touch them with the proverbial.
My very first PC was a Tiny many years ago. Mother in law has it now and it still works fine. Just don't try connecting to the internet with it as it only has a 14k modem.
ldgit:
I believe that Time bought out Tiny some years back and so are probably now made in the same place just have different badges.
I've just bought a new Dell, well pleased with it.
There's a couple of places around that will make them up for you. There's a guy on a small industrial estate between Brynmawr and Abertillery. Also you could try PC Doctors in Waunlwyd, Ebbw Vale. It's on the Cwm road above the Festival Site. Bet they'll be as cheap as anyone.
Word of warning about printers. They may look cheap, but they get you with the ink. We had a 'free' one with the Dell. Turns out the ink can only be bought from Dell and it costs £45 :evil: .
