I'm assuming that T-8 is the best choice, but have not decided whether
to go with the 4-bulb or 2-bulb (4 foot) fixtures. What factors do you
think should affect my choice concerning this, besides price
(obviously!).

The Indy Habitat for Humanity surplus store had a whole slew of T-5
fixtures (w/bulbs), new, in-box, when I was in there a month of so ago.
Don't remember the pricing, but it didn't strike me as much more the
the bare-nekkid flourescent fixtures at Lowes.

These had grating over the bulbs, which might be a asset in a shop.
