I've ordered a bunch of tooling from RDG (http://www.rdgtools.co.uk/), Chronos (http://www.chronos.ltd.uk/), and CTC (http://www.ctctools.biz/) for the lathe. There's at least one more of these deep-discount tool stores: http://www.arceurotrade.co.uk/. These stores sell tools of mostly Chinese origin, but I think they will do just fine for hobby use, and the price-level certainly is only a fraction of what European tooling costs. If anyone knows more of these let me know!
The first things to arrive were a set of center drills and this Glanze parting tool from Chronos. I've settled on only a "Myford-size" T00 tool-post which has holders for max. 13 mm tools.
