This.
Here's a list of morphs that are out there:

I'd keep an eye out for the basic morphs/base morphs seeing as you have a budget such as that.
Also, I'd recommend racks to those who have 4+ snakes at the least, otherwise it doesn't seem very useful. Not sure about the breeders in that area, but check out some of these:

There are many more, and quite a few of the users here are also really nice breeders
Good luck hunting for one!
