There are lots ofcombination gunsmade over the pond, but the least expensive will be the Russian made under the Bikal brand or the same model imported by Remington. They are acceptable "hunting quality" guns and not priced real high.
My first choise would be a used Valmet 412 and it came here (from Finland) in numerous rifle cals under a 12ga. bbl.. (includeing .243 Win.) They are still being made under the Tika brand (in Italy) and are now called 512's....
The Valmets are a world "higher quality" over the Savages, and i've seen them for reasonable prices considering there quality. They were mentto be"hunting guns" and they are VERY durable!
Nice thing about the Valmets is, they are switch bbl. guns and 26 different ones were made in double shotgun, combination rifle shotgun, and double rifle bbls... Every one could be bought seperate and put on your action...
I have several bbls. for my 412 and you can see some of them below...
