Coleman makes quite a few of these in variety of configuration. I use a brief case sized one with one burner and a grate. They make a two burner same sized. Readily available at many stores or on-line from Coleman. They go on sale occassionally--so shop!
I have found Coleman to stand behind their products 100% and be very helpful if things do not work correctly---which is seldom in my personal experience.
They replaced a four year old Roadtrip Grill for me that my dog had knocked over resulting in a part being broken---for 50 bucks they sent me an entire new stove. They really did not owe me anything.
My family has fifty year old Coleman products all working just fine. So I like 'em. I think you will as well.
