I've run Jebao's (WP-25 & RW-8) and replaced them with a Gyre, very happy with it so far.  There was a problem with the controller being too sensitive but it was replaced as soon as I notified the distributor. 
  
I don't think Gyres are expensive at all when you consider the number of powerheads it can replace.
