here is the thread with a list of just about all roms, pick your flavor between 2.1, 2.2, and 2.3 roms, just go to each thread and see what interests you, and your going to have to try different kernels to see which one works for you or ask in the thread of the rom you are using on which one is working the best and getting the best battery life.
