i have a gyre the flow is not much better than the vortechs, and it doesn't even come close to build quality of the vortechs, and probably wont last as long, im still running a original mp20 dry side, been going 5 years strait. its like comparing a reef octopus to a bubble king as far as build quality gose, maybe its not because of the gyre, wave, jebos or any other, maybe its to get rid of old stock to prepare for a new release, the mp 40 has had the same design since the beginning regardless if it was a mp20 box or not its still the same pump. im not taking ecotechs side here so lets not get it twisted, i thought they was over priced at $565, more reasonable at $395, but at $299 i wouldn't buy anything else. i wouldn't let this steer you away from there products, you cant expect everyone to be like Walmart. the costumer service and piece of mind knowing they will just about bend over backwards to get you back up and running is worth the premium they was charging, not to mention that even after the warranty is over you can still expect years of service out of the pump.
