BIN $29.95 - needs lid gasket, pulsator, inflations, hoses, pump
BIN $119 - needs pump
BIN $39.95 - gasket, vacuum hose, inflations (they also have them for other types of shells, at the same price)
Gaskets are CHEAP - $8.99 on eBay, cheaper at Parts Dept. As I said before, a NEW Interpuls pulsater will run you $89, + $19 for the adapter (if you go with a DeLaval lid, you won't need the adapter - I'm running with what I'm finding, here - DeLaval stuff is pricey!) Hoses - buy at your local hardware store, it'll be cheaper in the long run.
Pump....I found some on eBay last week for about $150, but I didn't check shipping (since we have a pump already...although my darling husband is talking about wanting a new one. :sigh: Not sure why, but....)
