Hi I am new here and I am looking to get either a ball or a RTB. I am learning a lot as I go but I want to get the different types of RTB's down before I decide which one I like best.

The smaller the better for me as I am new to snakes, but I am willing to learn everything I need to know before getting one so dont worry....newayz, I really like the looks of the surinam (BCC) ? especially, but the columbian is pretty and the brazilian. Someone told me that the surinam is a little bigger than the columbian is this a huge difference?

Also how much should I expect to spend on one of these? I've seen them around WI here for $150 plus or minus some.

What kind of home is best for one?...I am thinking of building a box type 4'x2' cage.
Any other important info would be great to know before sinking my teeth into my first snake!
THank you for all the help this forum is a huge help I love it!
