Reselling question, please help

[SchmidtSV76]

So my OG Droid crapped out on me. I wanted to wait for the SGSII or the Bionic but I don't have a choice. I picked up the LG Revolution and it's alright, but I'm planning on selling my phone when one of the aforementioned phones comes out and buying that one at retail. My question is, which would I be able to get more for, the Revolution or the Droid3, and how much do you think? I'm within my 14 days on the Revolution and am planning on going to exchange it today. Any help ASAP would be greatly appreciated!
