All the info I have came from this website. Lots of people here recommended a used Alcatel as a budget pump. The one I bought shipped from Massachusetts. I was almost going to ask if I could pick it up to save on shipping, but didn’t. It was one of the best packing jobs I’ve seen in a while. Expanding foam inside of plastic grocery bags, so it would have been almost impossible to damage during shipping.
Also lots of user info posted. This thread has flushing info
