Nope, no reason to get one at all.
If you get a C&R you will wind-up spending money for stuff you don't really need and with rare exception, will actually haul out to the range and shoot. You're gonna spend time looking for the best prices on outdated ammo calibers, looking for parts to match the item you already have just to make sure it is "more" authentic. You'll spend money on holsters, mags, clips, bayos, ammo, scope rings, and more.
The disease is deceptive, it starts slowly, usually something as harmless as looking though an issue of Shotgun News.
When the C&R disease bites you, it is a long and oftentimes painful disease to cure. Unfortunatly, I don't know of any C&R sufferer that has ever been cured - they've all died without being cured.
*** BEWARE - C&R disease is a horrible affliction! ***
