Never installed the stuff before, but considering it for a new property we've bought, where I can't trash the ceiling without her indoors getting the hump. It will be for the dining room part of a kitchen diner. I've seen there are loads of retailers, but it seems that apart from cheap tat kits, the issue is paying a fortune for some of the actual lights. Going to use a 3 circuit track, so we can vary the lighting levels. Any recommendations?
