Somewhat surprising to me but apparently you can now buy those little Neoden in the UK, from Blakell Europlacer of all places. I don't see them on the website but apparently £10-12k gets you one without the import hassle + support and training.
..but with the crappy Chinese software and dubious feeders, presumably.
From what I hear, importing them isn't too big a big deal. Proce seems to start around £8K with a few feeders.
The Neoden 4 or 5 ?
Well I doubt it is in any way custom. No idea which one it is but I think possibly it comes with the feeders with gears rather then a springy clip + pusher nozzle.
