If you're looking to abandon your existing carrier and move to Big Red, then the RAZR M is a great phone to choose for the transition. And now you can grab it from Amazon Wireless for only a penny (Black, White). That's a top-notch phone with Jelly Bean (4.1.x) for basically free - and it's still $99 at Verizon.
If, for some strange reason, you'd rather have an older model, Amazon Wireless is running a couple other device for a penny, like the RAZR MAXX and HTC Rezound. Not sure why'd you want to buy year-old tech on a two-year agreement, but hey - to each his own, I guess.
