I use RHP's in all my tanks (IJ's, Corn, BRB and Leo's), they are really nice. They provide a nice, even heat...radiant heat, not just hot bulb heat. They don't kill humidity either, it stays nice and high for the BRB and 'normal' for everyone else.
I got mine from Bob at Pro-products and couldn't be happier with them. There is a good information/compare/faq on the site.
