I was just in the market for the same thing. I wanted a bag that had some padding, but a pelican case or similar seemed like overkill. I wanted a messenger style bag that was sturdy but not too pricey. I ended up getting this bag, designed for cameras on clearance for $40 (normally ~$100). Manfrotto MB MS-M-IGR Messenger
It is a really nice bag, but it doesn't quite fit my Helix 9 and 999 as nicely as I would like. I have to remove the cover on the helix, and it is still a snug fit. I may actually keep the bag for my camera gear and keep looking.
I had not thought of the range bag route. That may be a better solution!
