Mark and John C,
I don't know about the fixtures, but LED bulbs have come way down in price in the last couple of years. Many are dimmable, but check them to be sure. We have now converted almost our entire house to LEDs. Some CFL & 4' florescents left, but incandescents have all been replaced.
Go up to Home Depot and have a look around. The selection and variety has greatly increased. They even have LED bulbs you can control color and brightness with your smart phone. I have been watching them at Home Depot for about 3 years now and I think you might be surprised at the prices and selection available. Some are nearing the prices of the better incandescent bulbs. Also consider that they last from around 12 to 22 years depending on brand and use just a fraction of power that incandescent bulbs use. In my case, I will probably be expired before the 22 year bulbs fail.
