Re: new gun???
For an inline, I've read and heard alot of good things about the huntsman from NEF/H&R
For a side lock in perccussion almost any gun, the choice should be dictated by what caliber and projectile you want to shoot, ie fast wist or slow twist barrel. IF you are looking for a flint gun, that's sort of a ford chevy thing. I prefer the Lyman among the production guns. Although sometimes you can get a custom gun on the used market for about the same price as a new TC or Lyman. I picked up a first rate custom gun for $425 about 5 years ago.
