Thanks to everyone for helping me make my decisions with my Amiga.
I bought an A1200 with faulty video, it worked through RGB but with a red tinge, which I wasn't really happy with. I don't have the tools or expertise to fix it myself so I'm going to send it away to someone who does.
I've bought a replacement motherboard which arrived yesterday.
Just put it all together.
A1200
Blizzard 030 @ 50Mhz with 32 MB
4GB CF HD
Easynet PCMCIA wifi card (which I have no idea about how to use or how to set up as I've only got Workbench installed and WHDLoad)
I bought a replacement second hand case and a brand new keyboard so that it looks almost as good as new, apart from the warped case at the bottom left, which I've noticed has happened to my brothers as well, must be a heat thing.
