How come so many vortechs for sale?

I've got one of the original MP40's. It's a good pump, lined up as perfectly as possible, but since day 1 it's been noisy. Flows a ton of water, random flow is nice, but I just can't get over the noise in my living room. Bzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz

I've started looking at my replacement options.
