Jay - I read your report and was interested to see that you ran your evaluation on a Heller 1500 5 zone. We have been hearing for some time that a larger machine (7 zone min)with higher temp heaters and fan motors would be required. Is yours a "hi t

Yeah, made from Durostone or Delmat would be perfect. Try buying some pieces and have them machined into tools or DIY. This is the same material that solder pallets are made from. http://www.boedeker.com/durost_p.htm http://www.polymerplastics.com/

We found BTU & Vitronics to be the best, The Vitronics looked a slightly better (and more expensive) machine, but on the other hand we've had completely trouble free operation from our old BTU's. Oh, and the fact that BTU are No.1 in the world, and
