personally, i would buy a good solid shovel and cut down the handle, or just buy a short shovel. these will shovel the most efficiently, and since you said its only going to be for shoveling, you don't have to worry about not having extra utility of edge.
You read my mind siguy... today stores are closed but I am going to check a few hardware stores and consider doing what you said: Finding one with the shape I like and probably cut down the handle. I will try to find one with D shaped handle... easier to grab with gloves on or mittens. I plan to mate it with a folding prunning saw so I don't need to chop with it which makes the edge usless.
Thanks a lot,
Mikel
