You are talking about a roasting pan? (When I hear roaster, I think of the big electric appliance my grandma had on her kitchen counter.)
You can spend a gazillion dollars on an expensive stainless steel one, or go for lower cost enamel ware or WalMart roasting pan. Almost anything that you could roast a cut of meat or poultry in could work on top of the stove--the only exception I can think of would be a glass pan.
I just haven't been the same
since that house fell on my sister.
