Low cost submersible DC pumps

There is a fairly new pump being sold widely that is approximately a $150 version of a Shurflo 9300. Search for "submersible solar well pump". It will run on anything from 12-24V at < 2.5 amps (contrary to 4A specs). Given that it's ~1/4 the cost, is it a good value for low usage?
I also see a number of made in China submersible 24-48V brushless centrifugal pumps. Price depends greatly on pressure needed, but say $700, ready to connect to solar panels. Any experience for higher duty cycles?

I'm going to try driving one with solar panels and only a simple DC->DC converter.

Any update on the performance of the $150 pump? I also have one on hand as a spare for my 9300"s. Any update would be appreciated.
Thks.

I haven't seen any reports of the number of hours people are getting. I suspect they should be considered semi-disposable.
