Two more questions to ask when comparing ballasts:

1.  Will it trip my gfi?   Most newer all-electronic ballasts will.  So you
lose the protection of your gfi.

2.  Will it cause a lot of rfi?   Most ballasts will.   It is pretty hard
to suppress without building an all metal hood (possibly with a plastic or
wood overlay).

These are the two problems I alluded to in my "dream" hood.
