Hmm.. I've just decided to go with in ceiling or pocket lights for my basement.. My floor joists are still open though so mounting is a bit easier.
The best price I've found so far is contractor 6 pack of lights at Home Depot for about 50$ for 5" and $75 for 6" (that's for all 6, not each). I think they will work as my main lighting.. plus I'll be putting them in pairs on dimmers, so I have lots of control over the lighting in different parts of the room.
