If the amount he spent on restoring/making over his gun scares off potential buyers and thereby keeps prices on such guns lower, I'm all for it.  

The re-coloring was not needed.  He got a good price on the bluing.  He could have had the chokes opened, or choke tubes installed, by Mike Orlen for a lot less.  Likewise opening the chambers (and maybe lengthening the forcing cones).  I dunno whether Mike has a dent raiser but I suspect he does;  $125 for a small dent strikes me as a little bit high, but not by much.  I paid a local smith $100 to have a dent raised and a thorough disassemble-and-inspect on an old hammergun.  He probably could have polished and opened the bores a bit by himself with a power drill and steel wool.
But, he went the retail, name-brand route and it's his money.
