It depends on your view of something "new" - if "new" to you is a visual morph not seen before...then get your credit card out, mortgage your home and head to Africa (when the locals find new visual morphs they have the phone numbers of the big breeders (NERD, Ralph, VPI, etc.) and they call them directly to offer up the new snake....for HUGE sums of money.
If on the other hand "new" is just something different that is genetic (slight color differences, unique patterns, etc.) also called dinking projects you can find these more readily. By buying from the big breeders who don't have time to prove them out...also you might get lucky with the lottery in this respect finding something different and taking the time to prove it out. These dinking projects can turn big results but be prepared for a long dedicated process.
If you are just looking to want to import directly don't bother...for them to even talk to you would need to be importing 10s of 1000's of them (and without the right contacts you will more than likely get scammed). My suggestion is to hook up with an already established importer and buy a large QTY from them (unopened crates)...but you need to have a home or plan for all of them.
If you are just looking for a few just do the lottery or buy CH once they arrive (they will be all over the internet come spring)
Hope this helps.
