It all depends on individual budgets, but you're not alone. I bought jebao's for my 22g initially, but soon realized I should've bought Tunze 6040's instead (which I did and still have them). For me, the wave engine made perfect sense. I already had a controller for the tank (apex) but there wasn't a way to connect the gyres directly to my apex and I would need to buy the wxm module to control the vortechs, but that still left me without being able to control the gyres, other than shutting them off during feeding or manually pushing the feed mode on their controller. Now I just put my return pump in feed mode, push a button on my toggle box and everything goes to feed mode. The wave engine really opened a lot of doors for me and now I just need to sell my vectra and buy a COR20, then it gets easier.
