Look around, there are occasionally .410"s used, besides most gun store will give 10% discount for cash, or throw in some ammo. Very few guns wear out, so look around for a good buy. I have a Savage 220 in .410 that I picked up last year for $70 cash, with a partial box of 3 inch shells thrown in. Rifled slugs in .410 are questionally effective on deer. A ss 20 gauge would be more effective and no more weight. All .410;s are full choke. Take an old ss 20, cut the barrel back to 26 inches, so no choke, and it's a very nice light grouse and rabbit gun. However the .410 is fun to shoot, and when you powder a clay target, it's very satisfying.
