If you buddies have BCA radios and you don't want to spend the money to buy one but still want a radio that is compatible, consider a Baofeng UV5r which is about $25 on Ebay.
It has more power, can upgrade antenna for more range, can program SAR, sheriffs, EMS, and other frequencies, and also has FM radio that you can listen to when riding. Works great with a $25 helmet mounted mic/speaker system.
Been using mine for sleds and ATVs in summer for past 3 years with no issues.
I couldn't justify the cost of a BCA radio.
