We went with integrated fixtures where possible and in total have spent $1,120 on those and LED bulbs. This includes our bathroom vanity and ceiling light, three exterior lights (including one motion sensor light), our dining light, and five just basic all the same fixtures. For the latter we went with Costco's Cloudraker lights - can't say enough good things about them.
Some folks might be inclined to suggest that we should have just upgraded lights as bulbs died or what have you - but with all the other renovations, it made sense just to do it all at once. I did keep all of the old fixtures that were pulled out and am going to try to sell them on my local classifieds site.
