It's a few years since I bought a C&B revolver, so I won't address prices, but here's what you'll need in a nutshell:
1) The revolver itself (duh!)
2) Appropriately sized round-balls for #1
3) Appropriate grade BP, pryrodex, etc for #1. FFFg for BP, P for pyrodex granules, don't know for Pyrodex pellets, never used 'em.
4) Powder measure, preferably adjustable
5) Chamber grease, Crisco or wonder-wads to prevent chain fires
6) Appropriately sized caps for #1
7) Cleaning rod, lube, jag, etc if you don't already have them.
8) Nipple wrench and pick for disassembly of revolver and clearing the nipples between shots.
Some newbies are intimidated by clean-up, no need. Hot water works best, I usually add a little Murphy's oil soap to it but that's just me. Hot water makes it dry faster.
