Hi Beth,
Personally, I like the easiness of the Tunze products. Just drop them in and plug them in. That's about it. While Ocean Motions are great products, and the owner Paul is great to deal with, I really didn't like all the plumbing that needed to be done on the 4 ways to have the routed the way I liked. Also, if space is going to be tight, then I don't suggest an OM wavemaker. Just my 2 cents.
