The basic one you ned is a 2M. The Licesence allows you to talk on multiple bands, so I got a dual bander. Tim and Chris have the next higher version the 8800 which allows you to use the radio as a repeater. Lots of threads on this.
Here is what I have and where I bought it. If your coming to the Rally Saturday you can check out Mine and others so you can see the different radios and what you can do with them.

K400CNMO -- NMO Deluxe mount. w/6.5' RG-316 Teflon coax & PL259.
SBB-5NMO -- Comet 2M/70cm Mobile Antenna (Black), 3.0/5.5 Gain, 38" Length, NMO Connector

You may need the 10Ft antenna extension cable dependent on where you mount the unit.
Also go on ebay look up seller W1Jim and buy the Yaesu cables (extension & aux audio extension) for $15. All high quality, 25'- more than enough. This is in place of the $75 extension kit sold elsewhere.
