GWI.net offers Lewiston and some places in the area there. They're also my land line Telco. You might want to check them out as they also offer phone service there on the Verizon copper. DSL and Phone together, you might do better with them than you did with Verizon.
They also have Maine based tech support and I've not had any problems. I used to have Adelphia Cable, it was... very painful.
