I'm in about the same boat, and I'll get my new pump (and tank, which is leaking and was never installed right anyways, apparently) installed on Friday. I'm way remote, so there's about $250 just in travel time for these guys, but they quoted me $2800 for the pump and tank and labor. Youch. It's also a 3 inch submersible, and it's only about 10 years old. Alas.
