Actually, if you keep them warm they start pretty reliably. My dad does some work for a local radio station, and they've keep warm oil pumping through it *all* the time, and keep the room where it's housed warm. (That's pretty easy to do considering the amount of heat the 100KW transmitter puts out. :) They haven't had a failure yet (since they started doing that) at the remote site, but they are also very careful about doing regular maintenance on it.
