Well for £100 you should be able to find a bargain on an EOS 30/33 - maybe even a newer 30V/33V. Or you could pick up an older 50/50E for about £50.
You can check out the EOS range here.
As for older cameras, I can't help you there other than to say that the EOS range doesn't have that 'interesting old camera' thang goin' on.
