any gun that you change to have the word "custom" now in its description....will have lost value....plus whatever you paid for the tinkering is now also flushed away.....if you care about maintaining the guns original value just remember that gunsmiths are for repairing....not changing
If you don't like the gun sell it and find one you do....
I agree - that's pretty much the case in the real world. I have a couple factory tubed guns and have had Briley tubed guns. I do not now and never will again have an aftermarket tubed gun. And I've seen some not exciting work from Briley. the real point for the OP is the money. Do you care that you're pissing away X$ for something that you don't even know you need and few others would want later if you don't? For me the whole sow's ear/silk purse thing ship has sailed.
But, your gun, your $.
have another day

PS - there is nothing that will remove a potential purchase from my consideration faster than aftermarket tubes. But that's just me.
