This is off topic....but since the people on this list know a lot I figured i might get an answer faster than searching a lot for one.... I wanted to know where to get a Peltier Junction.....and some info on Laser cooling.....But i'd really like to but a peltier junction.... I saw one that was one inch square for like 17 dollars...but that seemed expensive so i didn't buy one...and now i can't find any... John
