I have a 2010 Taylor x14 Deluxe case that my DMSM rested in with small dog case cover over it.
Not a mark on it , latches show small amount of tarnish , $175.00 shipped in the lower 48
You do realize that a brand new one is all over the web for only about $25 more and that with any sales it'd be the same price or even less than your old one, right?
As the OP found, cases are pretty cheap these days. A real Taylor case can be had for $100 - $125 used if you look around. Famous brand hard cases (SKB, TKL, etc) go for about that new (maximum) and if you look at the used market or "off brand" then we're way under $100.
