Ok, I'm located in Tennessee and can fill in a few facts.
1. If you buy a Amigakit a1200 you will get a good unit.
2. You will PAY alot for shipping from the UK.
3. Most games/demos are PAL instead of NTSC, so even if you get a ntsc 1200 you will have problems running some games unless you use a rgb monitor/flicker fixer.
4. Get a Amiga monitor, I use a 1084s and it displays NTSC/PAL just fine using rgb.
5. You will want an accelerator or a good ram card. The extra memory is needed for whdload.
6. Speaking of whdload, you will want to spend the money to register it. 30USD
I have an American and a Uk 1200. I modded the ntsc unit to be a pal unit. They work great with the ATX to amiga power adapter, much more reliable than the original power supply. One has a 68030/33 and the other a 68040/40. 4gb cf in one, 80gb hd in the other.
I'm about to sell my NTSC unit with 68030, so if you are interested in used drop me a pm.
Later,
