Indeed there are, but they seem to be getting more difficult to find.So the main point of this post is to say keep watching as there are bargains out there.
It must be about 8 years ago that I bought my present 1652, on eBay. I don't think I paid a lot over £100 for it, it looked (and still does) virtually 'new and unused' and, until a week or so ago, has given faultless service.
However, the last several to be sold on eBay have gone for appreciably more than £200, which was the sort of 'ceiling' I was hoping for. Indeed, the auctions often go to figures approaching (sometimes exceeding) the £240-£270 for which a number of places are offering 'Buy it Now' sales. So long as their people around willing to pay such prices, I'm obviously not going to find my 'bargain' unless they 'miss' one - but I will definitely keep trying!
As I've said before, what I'd really like to find is a 'for spares or repair' one with a dead display, since I think it very likely that I could then cobble together a working machine!
Kind Regards, John.
