This classic remains the best, most economical choice for car camping/trail cooking.  The knobs start out a little sticky, but you can solve that in five minutes: as mentioned in other reviews, disassemble / wipe off excess grease / reassemble.  Don't be sold on more expensive units that are twice as much (the ones painted red and come from the factory dented and warped) - the quality control on those units is awful and in the end, they do the same thing as this little beauty.  Save yourself some simoleons and purchase this rig.
