I've had 440Source ones. Many gave them a bad rap claiming the water passages were to small causing overheating. Yeah, they were a little small ... so I used a die grinder and opened them up. At the time you couldn't beat the price and some people are just "CHEAP CHINESE JUNK haters" and will complain about anything. I've see other brands - Mancini have most of them on display at shows they attend. Personally I still like the Mopar one best of all.
