I'll try to offer an honest assessment... hate to see someone new into TC's get taken.
IMO over priced when you add up the parts while not knowing a lot of factors that would make a difference. The ad tells you very little. I remember Vern, but that doesn't indicate just what he supposedly did to "customize" it. Just bolt-ons... more? Normally a "package deal" also means a savings for the buyer over buying it piecemeal. Used price is not new price - asking price is not always selling price.
Is the frame factory stock, or tuned, or had a trigger job? If so by whom? Makes from a few bucks to another few bucks more difference in what its worth, as does the vintage.
Barrel made by who and from what brand blank? SAAMI or a custom chamber? Makes a big difference in what they cost new/what they are worth used.
Williams sights for the Contender are something like $70-$80 new if I remember, so worth less used.
No idea whose this one is.. but Contender comp/brakes are available for as little as $35 to 3-4 times that depending on who's/config (and not needed on a 6X47 anyway).
As figured maple goes, this set combined doesn't have full coverage, spalt, etc, etc, etc so a select grade and not one of the exhibition grades.
Dies also vary widely by what brand, condition, etc. Can't remember what I sold my two sets for... maybe SlowSlim will know (don't remember if he bought one of them when he bought a 6X47 barrel from me).
YMMV, HTH
