Thanks for the advice, Chvid. Great advice. I did find a bionx PL-350 for $1664, which is about $200 less than the usual price. That might come in handy.
Some other things I have to figure out are power usage and draw (in terms of figuring out exactly how much power is being used). I heard that you can buy a device at Home Depot that you can plug into the wall and then plug a charger into that device, and it will tell you exactly how much electricity you used. The main point of this project is to do a six month analysis of the cost and benefit in comparison to a car. The project starts Monday with my weight, the price of gas (my car is on fumes right now, which is perfect), the amount of energy used, carbon footprint, etc. It will all get written up and reported. The students and I do the math, input the data, etc. I'm pretty excited, and the energy company is excited too.
