Why not build one yourself?
I made one from a cheap toaster oven and a custom built PCB. Or actually, from two cheap toaster ovens because one set of heaters showed to be to little.
It works really excellent. Just put in your PCBs press the button and open it when done. Up to now I've soldered at least 200 PCBs with at without one failing.
Currently I'm working on an improved version with a larger processor. The ATmega8 seemed to be to small for all the printf libs. And it's going to have a lasercut front panel with a small display and some buttons (and USB).
If your interested I could send you a copy of the new circuitboard. My PCB manufacturer will make at least three and I only need two. It's been designed for 230V but it will probably run as well on 110V.
Once the new design is finished I will post a complete overview of the build + tutorial on my website (www.anlagelab.net
