I've got a little Maycom AR-108 (about £60-70), and aside from being handy at airshows, it's very handy to get the ATIS before a 20 min drive to the airport to find out the wind has just picked up
It's also handy for when sitting around the club on a less than perfect day waiting for the weather to clear/wind to die down - at least you get to hear what's going on.
