Something that may also be a consideration, you may look into a travel case, probably of the lightweight softside variety. This would give you a set of wheels that is easy to maneuver, plus a little added protection for your clubs. They are pretty nice to have for the airport, I would imagine it would be as useful on a bus. Although make sure it is O.K. to take them on the bus prior to spending the money.
This would also give a later option if you start to travel.
I personally would recommend a Club Glove burstproof, which is the brand many pro's use. But they may be a little more than what you want to spend.

You can probably find them a little cheaper retail on the older model that I have, and still has the warranties as well as the wheels. Although for the price, you also likely want to consider if you have a safe place to keep the bag when you are playing.
