Howdy everyone,
just wanted to mention these guys:

I bought a 350w, 170w and 90w and am very pleased with the prices and quality. I've not performed any thorough testing on them yet so have no curves to show, but the 350w sure does produce ice within a few minutes. Thermal Enterprises supply datasheets on request, enough basic info to keep anyone happy.
Planing to run a 350w (or maybe the 170w) undervoltage with microprocessor controlled power supply that keeps coldplate temp below ambient but above dew point using humidity and temp sensors. Fun project in the works.
Regards,
