I've been looking at the Motorola, Kenwood, Cobra models. The Motorola Talkabout series seems to have really good reviews.
Qualities that would be important in order of importance:
1. Range
2. Battery life
3. Price
3. Sturdy structure
4. Vibrating call feature
5. Looks cool
The VHF radios are more expensive but they have a much better range.
