Had our generation 1 Prius battery rebuilt. Not many of the companies in this line of work seem to work on Gen 1's anymore. Also had the transmission fluid changed while we were at it (they do more than batteries!). We had a small glitch where the ECU was throwing out error codes afterwards, so Simon picked the car up from our house, identified and fixed the problem (an ancillary cable/connector that had deteriorated). Of course, this issue was fixed for free, plus, Simon threw in a free alignment (car was pulling to the right a little) to make up for the inconvenience. Overall, I was very happy with the experience. I communicated via voice, email, and texts, and in each case, he was very responsive. He was very patient answering all questions. If your Prius is in good shape mechanically, do yourself a favor and get the traction battery rebuilt/replaced. Battery tech gets better every year, and this keeps your car on the road longer, which is a form of recycling, and overall, keeps more money in your pocket in the long run.
