Good deal! You can find some amazing deals on Craigslist.
Be sure to give it a thorough disinfecting! I saw a large 2 x 2 x 4 locally that the guy said his Cham got sick and died in so I figured it just wasn't worth the risk (but I am super paranoid of such things).
Not that you don't know this but lots of newer keepers might read this and neglect that last simple safety precaution.
