Kitchen puck lights: two questions

[mikejurasw]

Hi everyone, I'm helping my sister with a kitchen "up-do" and her wish-list includes some sort of under cabinet puck lights for the countertop. I would like to get something decent...hardwired and switched.
First: any recommendations for brand/product?
Second: she has multiple, newly wired (the yellow stuff...) GFCI's in single boxes over the counter. Can I expand one of those to a double-gang, put in a switch for the puck lights, drawing power from the GFCI? If so, what's the best way to wire it?
Thanks!

One of the difficulties you will face, is overcoming, or a workaround for back splashes, as well as transitioning between cabinets groupings.

My preference would be low voltage LEDS.
