I have been visiting all the sites mentioned since I became interested in buying a hybrid, and I agree that greenybrid.com is the best. The people here seem genuinely friendly and interested in helping each other. I now visit this site almost every day, and the others much less frequently, if ever.
Thanks to everyone for creating such a welcoming community! I can't wait to "officially" join when I purchase a hybrid - in a few weeks, hopefully!
