$1800 for a hand-pump? Are you Bill Gates brother?
Here is one instance where you can thank the Chinese for constructing bascially the same pump for $40 USD ( Harbor Freight )
Heres what you do, buy a chinese hand pump off Harbor Freight or Northern Tool and see if your really going to enjoy the idea of hand pumping water from that far down.. If you dont mind it, go give Bison Pumps $1800 for a hand pump ( its your money do as you like ) If after awhile you relaize its not what you expected?? Go purchase a cheap gas generator and set your electric pump up to be used off that when need be.. GL
