How much could I go my Savannah for?

I have 2 savannah monitors, i have had them both since April this year. One of them is totally nice and gentle, I can hand feed him and he slowly take the food, etc. The other is alot more angry, he/she will bite at your fingers, feet, w/e. I hold them both the same, I am pretty much symetrical in what I nurture them/when I hold them/bathe them. The nice one has a bit bigger living area. He has around a 5 ft long,3 ft wide/tall enclosure. The other has about a 5 ft long, 2 ft towering, 2 ft wide enclosure. They are both about 2 ft. long and athletic from what I can tell. I was thinking of getting rid of the meaner one at a reptile expo or selling him. How much could I get for him/her whether I sold it? Or maybe what would be a good trade at a rep expo for something different? Are black throat monitors expensive?

Answers:    Reptile expos don't really do as many trades as inhabitants would think. You can probably get a good amount whether you sell the monitor and the cage together. Check out kingsnake.com you can put it on there.
