Since the Q7 didn't come with any sort of cover or bag, I have been looking for possible solutions. This is what I came up with and it cost me under $5.00.
I got this bag from Walmart for under $4.00. It is a computer accessory bag. The Q7 fits perfectly, but there was no padding. I got this sponge-like foam pads from Lowes. It was in the Insulation Section. It came in a very large roll for under $6.00. I used very little for this project, maybe about 50 cents worth at most.
I added the padding by turning the bag inside out and I cut slits at the bottom. The slits can be resewn by hand. I haven't gotten around to that yet. Also the padding is about 1/8" thick so I glued two together to make it thicker.
Here are some other pictures so you can get an idea of the fit.

As a side note I also saw a black neoprene computer accessory bag there also and the Q7 fits great in that one also. The cost I believe was $3.86
