What type of snake is best for me?

[mrspicynacho]

Hi,
I'm new to this forum and new to snake ownership.
That said, I'm not entirely new to herpetology, I've owned geckos before and I have a decent amount of experience with handling snakes.

So, I'm probably posting this in the wrong place, but:
What type (breed?) of snake would you recommend for me?
These are my requirements:
-less than 5 ft long full grown (male)
-not too aggressive, won't be handled too much but I want something I can be comfortable holding
-under $100 (not including shipping if I purchase it online)
-can tolerate high heat (90+ degrees sometimes in the summer) and low humidity

Okay, those are my basic requirements for it, but appearance is also a large factor for me. I think most people would recommend a corn snake for someone like me, but there's just something about corns that I'm just not a big fan of. With all of the morphs out there, none of them are particularly attractive to me. I also don't like the appearance of ball pythons, how their head is significantly smaller than the girth of the body. I like kings and boas the best, but they each have some considerable drawbacks, like the "aggression" of kings and the size and price of some boas.

What do you guys think? My 2 favorite options at the moment are a Mexican black kingsnake or some sort of dwarf boa. I also love Colombian rainbow boas, but I wouldn't get one due to their humidity requiremenrs.

Thanks in advancd
