What are my options when upgrading a kids DSXL to a 3DSXL?

Well I found a 3DSXL for 140 with Pokemon black 2 on craigslist. I will probably try to sell my DSXL or gamestop it if they will give me more. If they give more then I may buy new. Will have to see what they give me.

I'm not sure if they still have the program going on where you can "upgrade" to a 3DSXL. If they do, that should give you even more trade-in credit.
