I have only used this a couple of times to transfer beer form carboys. here is a link to the product at MoreBeerhttp://morebeer.com/view_product/17305/103556/Self-Priming_Diaphragm_Pump_for_Beer_Transfers
you can see new it is $139 looking to get $100 shipped to the lower 48.
Any particular reason you don't want it? Just curious if you found any challenges with it, etc. I've been looking at getting this pump, so if its still for sale i might be interested.
