+4 on building your own in a tackle box....
Get a good one piece rod. (one for pistol, one for rifle)
Jag set.
Bronze brush set.
.22 and .45 patches (pretty much covers every caliber).
5 packs of bronze brushes for the calibers you use the most.
Bore cleaner and oil of your choice....
That will pretty much get anyone started, build off that as you get more calibers.....
You will never regret the little extra it costs you in the beginning. Plenty of guys here can tell you about cheap cleaning rods and "universal" cleaning kits that wind up in the garbage.
