To OP: if I were in the hunt for an FP3 style machine, I would go for the latest model you could aquire, the DC feed is very useful, infinitely variable speed and very convenient. Actually, I would be looking at a new FPS machine like the FPS 630M-NC. There are many classes of machining problems that just can only be done with CNC. And while the idea of having both manual and CNC on the same machine is attractive, these days having manual only can limit what you can make.
AND, I'd also recommend you look at Kunzmann, very similar to the Deckel machines but all modern configuration and backed by an excellent company (now owned by Weiller who do the best manual lathes in germany). Kunzmann FYI has USA distributor (Monarch Lathes, who also source the Weiller lathes as well).
