Best prices for dome fixtures with ceramic base is a farm supply store like Theisens. They'll also have cheap BR40 basking bulbs designed for chickens. For UVB I'd go with LightYourReptiles for high quality which is important. If you need nighttime heat I'd get a heat projection bulb from Megaray. They produce heat without visible light just as the CHEs do but without getting so hot (less fire hazard). Most of the rest I get from Amazon.
