Anyone found a quality submersible for 100-150 ft wells that is worth buying? The Grundfos seem to be about 3 times an affordable price.
How German of them.
3/4 HP is probably enough to trickle fill 50 ga a day,yes?

When I compared 1/2 horsepower pumps the Grundfos was 5 times the price of the Made in China one at a local vendor in Thailand, I opted for the cheaper one ~$100, figuring the pump should last the one year warranty, that was 4 years ago. The quality of the water will have an effect on life expectancy, my water is extremely clean and free of grit.
Ultimately you pays your money and takes your chances, based on experience with Grundfos circulation pumps, they are extremely reliable, wether that crosses over to well pumps I couldn't say, but would expect it does.

I was looking at RPS pumps, they want over 1250 dollars just for the pump and its made in china, likely at the same factory as the other ones. The bury that fact deep into the web page and claim its right beside the john deer china factory. Like it somehow lends quality to them. Lots of America this and that all over the page. I have yet to find a cost effective solution. I thought about a brumby pump or airlift pump but I'm not sure it will work because of the long horizontal distance between the pump and house. Manual well pumps also require heavy duty and expensive components. 400 ft of head pressure is a lot.
Edit: Just a tip, if you have a shallow well or even a well under 100 ft you can use a jet pump and modify it to run off a belt. Its actually very easy. slap on a 12/24/48 volt motor and a pwm controller and you have a more solar friendly and above ground pump. Easier to service.
