This is the case in point. Is a D 35 worth a neck reset? As a guitar, certainly. As an investment, no. You should never buy one as an investment unless you are looking twenty years ahead. It wasn't that long ago a D 18 in need of work could be had for $900. But you could by a used one for $1200. Would I want to have $1900 in a Guild D 35? Well, 73 would be the last year I'd consider it.
I rotate three guitars, one at a time for two to four weeks, just whenever I want a change. My Guild follows my Martin D 35. It is quite the contrast what with a Martin Rosewood dread being what it is and all, but when I switch, there is no going back. The Guild does it's own thing in just as satisfying a way, and when it's time to play the Texan, it's an, oh yeah baby moment from the first bass run. Do I put a monetary value on them? No. In that sense, to me, my Guild is worth as much as my Texan, though I have two grand more in the Texan. So if I like it as much, why wouldn't I have $1900 in it all in?
A friend has about six to eight guitars, most in the $5-8K range. He recently bought a standard D 18. He's selling a 1939 Martin D 18 Aged Authentic. That tells you one guy trusts what he likes. YMMV. You need to know when you'd like something better that what the general consensus is. The general consensus means squat.
