44mag for the exact reason you said...ammo is everywhere and cheap compared to the other options. Roll your own ammo, and save some serious money. I load my target loads for about .15 cents (not counting brass). 33 cents if you want to count new starline brass.
I love my marlin 1894 in 44. It wears a 3 to 9x40 scope.
