Ask yourself what you're going to do with it. I've had several Renegades over the years and one 1"/.54 cal Hawken and sold them all. I kept two 15/16" Hawkens and I shoot one of them *maybe* once per year.
I had a Seneca in .45 once and sold it. I wish I'd kept it. I got a wild hair about wanting a more accurate caplock for moderate distances (like 75-150 yards) so I sold the Seneca that didn't have a tang drilled for a peep sight. Then I actually shot my Hawkens (one factory .50 barrel, one GM LRH .50 barrel) with peep sights and realized that at the end of the day with my eyesight, open sights of any sort, even peep sights, in the deer woods in low light, are a 75-yard proposition at best, and I should have kept the Seneca.
At the end of the day the Seneca was probably the prettiest caplock TC ever made and they are light and fun to play with. They don't handle big powder charges but I don't think you need them at the typical ranges where they shine, or if strictly target shooting. Or hanging over the fireplace.
T/C caplocks are terrible reproductions of 'real' Hawkens but they are perhaps something even more interesting - living pieces of history themselves - if you count the 1970's as history.
I've been all over the world and hunted several states and shot elk and had adventures but none compare to what was in my imagination when I got those T/C catalogs as a kid. Cougars and wild boars and bears, oh, my.
