The Kühling brothers (http://kuehlingkuehling.de/
) just released a new model of their RepRap Industrial printer: HT500
Look at their new hot end... what a beauty. In combination with their heated chamber (up to 70 °C) you can truly make use from the max. 500°C (!!!) temperature.
Here's the link: http://kuehlingkuehling.de/shop/ht500-3d-printer/
Special introductory price is 9.990 €, which is possibly a bit above a normal Joe's budget ;-) But for small businesses or bigger ones it could be a great fit.
EDIT: Mixed up heated bed and heated chamber temperature! It's 70 °C for the chamber and 130 °C for the bed itself.
