I was never a fan of the mp40s in the beginning, mainly due to cost. However, after owning 1... I bought 2 more. I had the Jebaos & Gyres, and I tell you, the ease of cleaning the mp40 got me sold. I don't have to disconnect any wires or bring a bucket of water/vinegar into my living room to have it soak if I didn't want to unplug everything. It made it all worth it. Just power down the pump, pop the wetside off, drop in some water with citric acid and a few hours later, toothbrush it slightly, rinse and back in business. That made it all worth it to me.
