The place I am looking to purchase doesn't even have that 2227, so it must be pricey. They have the 2224 selling for $139.99.
I will definitely look into it though. Currently, I have 3 power heads going with my PS. I have a lot of current in there, but if I could remove them, it sure would save a lot of space and cleaning.
I went diving in Thailand last week and seeing them in the Ocean sure is a lot cheaper than keeping them at home.
Later-
