I'm in the same position, I haven't had anything to sell, but I can give the (somewhat voracious) consumer viewpoint. As a shopper I don't even bother with CL for the same reasons, in my mind CL=rescues (I know this isn't always the case, but a lot of people do seem to go there to dump unwanted animals). I do most of my shopping on kingsnake, it's fairly easy to use the search function to find what I'm looking for genetically and do price/quality comparisons. I do however expect a link to a website on a kingsnake ad, and if the website looks shoddy I don't buy. I expect a professional quality website from a professional breeder. So my vote would be split between kingsnake and websites.
Just so I understand, you look for professional breeders with professional websites that use a paid classified service and that offer top quality snakes - the best of everything. And for all that you are willing to pay top dollar, even over market value, right?
