I'm currently flying out of Bourn and really enjoying it. Nice club, nice aircraft and the club/instructors are good too. If you take the Gold Membership you'll find the hire rates are very cheap.
It is also nice to be flying out of a (relatively) quiet airfield without the full ATC. It is a bit different using their shorter runways that aren't quite as smooth as Cambridge.
Worth giving it a go in my opinion.
