Yep, MPJA is a pretty good company to deal with, mostly buy power supplies. I can get the exact same supply for $14.00 I was paying over $50.00 for from DigiKey. They also have variacs if you want to build a foam cutter, although I don't reccommend using a variac without an isolation transformer. To do it right they offer several high amprage variable DC supplies. More expensive but lotts safer.
