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 "China 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.
