The problem with the Beckson pump is the hose is to short when filling buckets. The hose also gets brittle even after cleaning it every use.... it would eventually crack or break in storage. (It has been a while since I used a hand pump though.)
I would just go cheap and purchase this pump:

The handle is flexible. But it is annoying to pump.... but it usually worked. Unless you broke or lost the hose.
If you are spending around $50 I would purchase a New Zealand hand pump.... I have no clue if they are any good. But I talked to the owner and he was super nice and he said his pumps are the best. LOL

He also recommended Jobe float valve to me which I believe is a good recommendation.
