I was able get a 1200 off ebay for £45 about 2 months ago. As it was local, the seller even brought it round to my house, personal delivery.
It was just the base unit though, and completely untested - yellowed but it was very clean and works great. It worked out but I was prepared for it to be full of dead bugs and non-functional, though.
They had an untested 600 too for 20 quid, but I had to pass on it.
