I dont think that running it over would be the best choice for you if your unsatisfied.
Selling it in the "equip for sale forum" would be best. I can guarantee someone will buy it for the right price.
Seios, Hydors, Tunzes, etc do chatter when they start up from a dead stop. Maxi jets do pretty well wiht that type of wave maker. A couple of those may do the trick for you depending on the size of your tank. Otherwise Seio and Tunze (for example) make wave controllers that cycle pumps from near 10-100% to prolong life and avoid start up chatter.
You could always use a CL system with a wave maker as another option.
