Which models and brands of electronic ballasts are reliable that run F40T12? What about for F32T8? (not necessarily compatible with both) I'm looking for reliable electronic ballasts for my collection that can take abuse like running in extreme temps, eol lamps for long periods of time, etc.

I've heard the Motorola ballasts are reliable but which model numbers specifically? Also I heard Fulham workhorses are good too.

For F32T8 I like the Sylvania Quicktronics, particularly the ones made around 2005-2010. The older 120v only Advance F32T8 ballasts were pretty decent too.
