I have the Oceansmotions and I really like it. It works well and I have not had any problems with it. It has been running since early April. I guess you could make something to work like it does, but I doubt it would be as easy and I would thing that the SW environment would prove to be very tough for the parts.

The only drawback to the Oceansmotions is that is requires a great deal of plumbing and that can be a little tedious, but once it is in, it works great.
