Cheapest/Best Bike to Bike Radio

[Llama]

Hi all
I have an autocom system fitted beneath my seat and I will eventually want to add a bike to 2 cars radio facility for an upcoming overseas (morocco)trip.

Both cars are equipped with CB and Am Radio VHF (2m) or can have handheld PMRs.

I'm a tight git so I dont want to spend a lot. Has anyone got any good recommendations for a unit(s) which can fit on the bike (preferably using bike power). It doesnt have to be very elaborate or have a fantastic range its just so that I can talk with the drivers en route.

All recommendation greatly appreciated

I bought a 2 pack of Cobra PMR radios for £29.99 six months ago. You may find them even cheaper now, just do a search on froogle. Limted to about 2 miles range but worth the money IMHO
