Bill I think you were taken, especially if there was nothing visually wrong with the pipe or cable. PE has been used for 50 years and down to 500'. If you should go back to PE, use 160 psi rated 1". There's n reason to go to 1.25", which you probably have because your pump will have a 1.25" outlet.
Since you have a leak the water will run out of the pipe as you pull it, at least down to the leak and it might be the check valve so the whole thing will weigh less. Two guys should be able to lift it and you could buy a Steel vise-type grip wrench to hold it from falling down the well when you unscrew each section.
Here's the wrench.
