I bought my CS-PPC for £900 when it was new. It was the top of the range (then) 200MHz one, and naturally has an early serial number.
My A1 running OS4 is great - my Sam 440ep is a lovely machine - but the A4000 is the one I'm most attached to.
Right now I'm playing Ultima VII on it via PC-Task, using the 68060.
It's still an awesome machine, and no NG Amiga or Mac will take that away from it - there's just something about it being an actual Amiga in hardware as well as software that makes it really special.
I was paying off what I borrowed for it for a year but I've never regretted it at all.
