So what radio setup would everyone recommend? UHF, AM, Single Side Band, smoke signals??

Is it best to buy a 'pair' or PRS handhelds or something mounted in the truck? what about scanning capabilities or is it best to get a 'fixed' frequency unit?
What brand? is Uniden or Tait better than the imported cheapies off trademe?
And of course, price is a factor (isn't it always) so where should I buy from? Who am I likely to get the best deal from?
