I would have been eager for the chance, depending upon the brand and price, if it were not for recent second-hand experiences. One of the guys I hunt with regularly has a Khales (forget the model it it's near top line) which has served him well for about 25 years on a 7mag. It has been out of commission for the last two seasons as first, the seals inside decayed
And the optic fogged up. He sent it to Kahles for a refurb and about 7 months later git it back and no the adjustments aren't true and won't hold zero. Back from refurb again and still not up to snuff.
But this is just one bad example, not indicative of all scopes of that age. Still it has too be a steep discount for me to want to roll the dice.
