Driving without hybrid system????

I know this thread is several years old, but I'm hoping you're still on here! Where did you take your Prius to get worked on? I'm looking at a different but also expensive issue (C1391 code, probably needs a new actuator and/or accumulator), and I live near-ish to Binghamton. I'm having trouble finding an independent mechanic who will work on a Prius. Thanks!
