Don, those are sunsun pump's rebranded as cv. I've been running them for 8mths now. The second generation with the ceramic shafts are great. The first generation with stainless steel shafts sucked as they rusted and had leaky voltage probs, much like the koralia's. I think they used 18-8 stainless on there first shafts, which is a nono in SW use. I run the 3000gph one's. They are quiet, pretty efficient (24w) and restart in the right direction 90% of the time. I would not run them on wavemakers as they will be like running the koralia's on wavemakers, chattering and what not. You can source them from china for 28bux + 10 shipping. HTH
