I've been looking for an "affordable" hand pump for my well in case power goes out for an extended period of time.

My well is >400 feet deep and the water level is at about 85 feet (plenty of storage). I can't do any kind of suction from that depth, so it's either a mechanical pump or straight up bailing it out. I'd rather have some sort of pump, but not one that runs off a generator. A good old arm powered unit is what I'm looking for.

Anyone have any experience with depths like this? I have seen pumps ranging from about $300 (look cheap as hell) on up to thousands. I'm looking for recommendations.

(Also, I did a search. Got timed out 3x, so decided to post. So sorry if it's a repost)
