could use a few suggestions

[latazyo]

I'm looking into picking up a fully terrestrial tort here and am looking for a few suggestions

A) species
I'm not looking to spend much on the turle, hopefully around 30-50 dollars for the animal
B) location
in another post I read that it is recommended not to purchase from a pet store, so where do you all purchase yours from?
C) requirements
what are the enclosure requirements for terrestrial animals, such as lighting, heat, substrate, size
D) feeding

I have had a RES for 11 years, but I must say that I don't know anything about box turtles or similar animals

any advice or linking to sites would be much appreciated

TIA
