Anyone have any tips on how to get a good deal on the SprintPCS 8703?

I'm an existing SprintPCS customer who's not under contract. I only subscribe to voice service, but would be adding BB service as well (replacing one of my two phone lines with the BB). I'm willing to sign a 1 year agreement, but not a 2 year agreement. Both of my phones are almost 2 years old.

I also have a business discount on my phone plan, so I could coordinate through a business person if that helps...

Thanks,
PB
