I finally found a perfect heater for my etch-tank... It's a Akva-Stabil submersible heater, rated at 150W! (www.akvastabil.dk) Price was about $36 (US) and it is completely submersible. The box said it had a temp range of 18-33*C (65-91*F) but the dial isn't locked so you can turn it further with no modification necessary. Cranked all the way up it gets a 2 litre tank from 10*C up to 45*C in about 30 minutes. There are no metal on it that can corrode or get eaten by acid and it is 100% sealed. I absolutely reccommend this one if you need a heater. KreAture -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY!
