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.
