I want to remind everyone who plans on making the run, a VHF radio is MANDATORY. There are many turns on this run and it is way to easy to get separated from the group even if you have GPS. Unfortunately, there's no way around this cost if you don't have one and wish to attend.
For those who still need radios, here's a link to Treypal's group buy. He's still selling them at this pricing I believe. I recommend getting the mounted Icom unit but a handheld will do.

And here's another option BlueSVT posted up earlier. Best option IMO as long as you don't mind modifying it.

I've also shared this info, which may be helpful to some that want to save some cash, and have a little more flexibility.
My buddy has had GREAT experience with this radio, the Yaesu FT-2900R:
Amazon.com: Yaesu FT-2900R 75 Watt 2 Meter VHF Mobile Transceiver Amateur Ham Radio: Car Electronics
Only catch if you read the fine print is that it only "receives" communication between frequencies 136-174Mhz and we run on 151.625. HOWEVER! There is a simple "mod" you can do to the radio, which unlocks transmitting AND receiving on the entire range! That's what my buddy did... works perfect, and you can type in any frequency you want to transmit on, at any time! Which is very nice...
Here is a "how-to" on the modification (supposedly not legal in the eyes of the FCC)...
Yaesu ft-2900r frequency modification mars mod
So for $220, you can have a full function 75-watt radio which works across a very broad spectrum, and you can type in you own frequencies! Many other models (most in fact) require that you program channels in those ranges.
Hope that helps! We've done dozens of runs... so my recommendations come after experience with a variety of plotters and radios.
Hell Noah, maybe you should invest in the Yeasu ones too, mod them (link above) and then sell to members already modified... just don't announce that you're selling them modded on the forum publicly! LOL
