There is a good underlying point in this thread.....
If you're experienced enough to do your own gunsmithing work (or have a friend who will at little/no charge), such as reducing a 6-12 lb factory or old military action's trigger down to a safe 3-4 lbs that breaks cleanly, then this could be a good proposition.
If one has to drop-off or even pay to ship (both-ways) to a professional, you could be better off spending that cash up front on a double-set gun, even if it is a different model.
I have freinds who've laid-out the price of a Shilo Sharps to have a low-dollar military rolling block action contoured, rebarreled, stocked, re-cased and have the trigger tuned or single-set installed. Their rationale was they did this in increments, and didn't have to put the $$ out all at once.....but their projects took several years, too....years they waited instead of shooting.
Might be some deals on used guns if you keep an eye out.
