Just spent 6 months agonizing over whether to buy a 20 gauge used VG+ Winchester 101 for $1,000 or a brand new 20 gauge CZ Sharptail SXS for $1,000.
Ended up buying the Winchester. I could not be happier. Quality and grain of walnut, fit, finish, checkering and bluing is beautiful. Far far exceeds the quality of the Sharptail. (And, the wood and finish on the Sharptail is just plain "blah"). Love the ejectors on the 101, so I don't have to dig the shells out with my fingernails.
Saw lots of nice Ithaca/SKB sxs, but they were around $1,200 to $1,500 in VG+ condition, and I just never cared for the orange tint color of the wood. Excellent guns though. A bit on the heavy side.
