How much would a new Verizon phone be?

So I got my Glide back in October, my upgrade wasn't til January 1st but they still let me have the upgrade. Just out of curiousity, I was wondering how much it would be to get a new phone like the dare or the new blackberry? And would they let me use my upgrade again? And if my touch screen is faulty would that lower the price at all? Please answer. Thank you.
