I see no reason to spend $50 on a 3-lamp ballast. Efficiency is good, but
warranties matter more, IMO. I've had a couple of electronic ballasts burn
out in less than a year. They might not be as efficient, but you could buy 3
of those Triad ballasts for every one of those LFS ballasts.

Yes, but I see no reason to use those either.  :)
