I bought one @ Wal mart, put a regulator on it, set the temp & marked it @ 105 degrees & it has worked flawless for six months. I also bought a plastic cake plate top (looks like Hos Cartwright's hat)so I would not have to cut the plastic trays. I paid approx.$40.00 bucks for it.I shoot a lot of enamels & the dehydrator cuts the gassing out process to eight hours or over night.
