I am a mobile DJ and I want to consolidate all of my misc crap into 1 or 2 bags. I already have a laptop bag. I keep my laptop, vinyl controllers, notes, pens, business cards, mic, etc in. Now I need a bag for my cables, tape, tool kit, spare parts, etc. Need something that can hold a good amount of weight, cables are heavy. Preferably in black. i was thinking of just heading out to the surplus store and picking up something from there. but wanted to see what other options are out there before I do that.
