I also run a few jebaos for additional turbulant flow. I think the higher quantity of stops and starts from my programming does a number on these pumps and I too replace them every year or so. My MP40's have been going strong for 4 years so far.. While they haven't broken even vs the jebao yet, it sure is close..
I did just try one of the jebao gyres in my frag tank (48x24x12) and am surprised by the amount of water it moves.
If I was on a budget, I would likely continue on using the Jebao.. A gyre and a powerhead on random for tubulant flow might be a good combo. If you want something that will last longer, try looking at the Tunze powerheads.
