It really depends on your budget and what you can afford.

On the affordable side, there are Pastels, Mojaves, Spiders, Pinstripes, you get the idea.

A bit more expensive would be things like Lessers, Albinos, Pastel Yellowbellies, etc.

More expensive than that would start getting you Pieds, Clowns, and so on.

So really, it's up to you.
