Because I have been shooting for over 60 years, I have a few.
I just picked up a new one on sale at WM for $20. Everything from 10GA to .17. Three different brass break-down rods, two handles, brass brushes, cotton swabs, adapters for all the tips, about 12 different jags, patches and large wiping cloth. No chemicals, aw shucks.
All the rest of the stuff I've collected over the years is in 3 different tool boxes or ammo cans.
