well, I dunno. If making it shorter means stacking in the container, and if putting more cookers in the container makes for less costly shipping, and the price is part of the lure for a somewhat smaller cooker (face it, it's still not portable, and a person can cook small on the big one just as easily as on a smaller one), then make it shorter.
Also, if size is part of the lure for some (available space is limited), then maybe a shorter cooker would be helpful.
I agree that it's easier not to have to bend over, but maybe someone could develop plans for a stable platform for a smaller cooker, to make it counter height. Win win - Dennis gets less expensive shipping and less cost for tile, etc. (passed on to happy customer), and customer can raise the height however much.
But I think Dennis should take advantage of cost savings, if possible.
