Lenny,
Connecticut Valley Manufacturing makes the best forstner bits I have used. They are not inexpensive. You will pay the price of a whole set of Chinese bits for one or two of these. They make clean cuts with no burning.
When I first started using forstner bits, I bought several very cheap ones made in China. They burned the wood, and I spent too much time sanding out the burned wood.
I have some of the Freud carbide forstner bits and they are good. Clean cuts with no burning.
