Many Asian ratsnakes make good pets, are extremely hardy, and handle very well. The Chinese twin-spotted ratsnake makes a great pet. Not many breeders deal with them, however, so they aren't very well known. This is a gravid female that we call the blonde phase, and there's a number of other color variations....

Other great pets are the various Steppes ratsnakes, Russian ratsnakes, Mandarin ratsnakes, and several ssps. of stripe-tailed ratsnakes. Corn snakes and Great Plains ratsnakes are some of the greatest pet snakes in the world, of course. There are many breeders that specialize in most of these species.
I'll add a link to my photo gallery, in case you want to look at some more photos.
