For flourescent I just started using Juno, the model # stats with U. I used to use alko little inch, but they are expensive. The juno is about 1/3 the cost. It is also 1/2 the size. It uses an electronic ballast and has a 3000k lamp included. I also used these for over cabinet lights as well.
WAC makes a zenon undercab with a hi-low switch that is nice and fairly cost effective.
For a continious light strip, dimmable, your best bet is seagull ambiance. I like to use 24v 10w frosted festoon lamps. This is probably the best cost effective way to do it. Seagull can also be used on the rails fopr "in cab" lights
