Hi Michelle,
If you are only going to have one snake I say go with a jungle carpet for two reasons.
1) Size-wise they are right in the middle range of carpet pythons....bigger than Irian Jayas and smaller than coastals. IMO they are a perfect sized python, just big enough to be impressive, but small enough to be easily managable.
2)Jungles are beautiful!! It is hard to beat the "OoooHH" factor of a nice black and yellow jungle. Even people who know nothing about snakes are awed by the sight of a nice trophy jungle. You'll pay more for the nicer ones, but it is worth it!!
You might want to check out the NARBC show in Tinley Park.

This is a HUGE (look at the vendor list) reptile show that is held annually in the Chicago area.
