Just looking at the page of secondhand machinery, inside the back page of the latest ME, a Myford ML 7 @ 1125 UK pounds, to super7 2450, and a super 7B for 3450 UK pounds, from my point of veiw, only a nut case would pay those prices, you could get an industrial type for less, or a number of new Chinese ones.My own lathe is a bigger Taiwanese belt head one, I could have bought a Myford for about three times the price(with discounts it would actually be nearer four times), That was over 20years ago, and I'm still happy with it.
Take your time, and choose well, you proberbly won't get everything you want. Ian S C
