Welcome to the forum djc. I a confused as to why you wouldn't consider any steel stoves but you are looking at Woodstocks steel stove. The big plus of soapstone to me is that it evens out the heat. The con's are that the stone could crack, it takes longer to heat up, (not too long IMO) and eventually you'll have to rebuild it. If you have to go with one stove I wouldn't go any smaller than a 4 cu. firebox.
