Thanks so much all!
After thinking it over, and reading your replies, I'm really leaning towards the Pedersoli Rocket Mountain Hawken in .54 caliber with maple wood stock.
Like I mentioned, I handled this model (but in .50 cal) at a local Cabelas, and the fit and finish was just terrific. I sat there holding it and gazing at it for a good five minutes or more. Super impressed. I know I could get the Lyman GPR... but they just don't look this pretty and from what I read, don't shoot quite as well.
I still would LOVE to get an 1861 Springfield someday, but this Hawken seems like it would be more up my alley and just more convenient all around. I remember a few months back the Pedersoli Hawkens were on sale at Cabela's website for something like $950. Dang I should have jumped on that!!
Thanks for the help guys, I'll be looking out for this gun and when I can get one for a good price, I'll bite the bullet and nab it.
