Since you are looking for a user you can find many cheep. It's only when you want NIB (correct shieth and paperwork) you will have to get close to the hundred mark. And then as soon as you use/sharpen 1/3 to 1/2 the 'value' goes away just like a car. Flat frame no nail nick 112's were made in the 10's of thousands.
Frankly 420 in a recent issue is just as good a user or even step up to S30V. The real rarity is a finger grooved 2 dot. Early 112's are NOT as collected as 110's and values lag far behind. If you like nickel silver frames Buck just made a run of drop points in both 420 and S30V which were never made way back then.
The old blade grinds in 440C were also very thick behind the edge. I have a 2-dot, pictured below, and have loved the aesthetics & the heft of it. But getting it to cut well, by thinning the grind behind the edge, was a big project and it's still not as thinned out as the newer factory grinds from Buck.
The best thing the new Bucks have going for them is the improved grind on their blades. Much better cutting straight from the factory with thinner primary grinds and more acute edge geometry by spec. And they sharpen up beautifully and easily. I also have a later model 4-dot with the finger-grooved handle (3rd & 4th pictures below) and its primary grind is considerably thinner than the 2-dots. Compares very similarly with its 425M blade, in terms of cutting geometry and ease of sharpening, to the more recent Bucks in 420HC. And ergonomically, the finger-grooved handle is the most comfortable of any knife I've held.

I attribute that to the large chromium carbides and maybe also coarser grain size, in 440C. I think it's known that either or both of those factors will usually reduce toughness, making it more prone to breakage, chipping, etc. The carbides make it tricky to thin out the apex as much as I'd want while still maintaining edge stability. I have the same overall impression of 440C as you've mentioned - and it's also made me drift away from that steel in favor of the others (420HC, 425M & S30V), all of which don't have the same issues with carbide size in particular, if not also grain size. I'm spoiled for thin edges on all my knives, which is why I'll always favor steels with finer grain, even if that means they're not as wear-resistant.Years ago I acquired some old 440C 110s and 112s via the big auction site. I did the same thing with reprofiling the edge to get it as thin as possible and the results were disappointing across the board. I don't know if it's due to carbide size, grain size, or what, but when I tried to go really thin (like you can with 420HC, 425M, S30V, etc.), it seemed like the apex would just "disappear." It's what soured me on 440C.

The 2-dot 112 I pictured earlier, I thinned it out on SiC sandpaper, which also convexed the grind behind the edge. I then took it higher in grit on the sandpaper for polishing that convex, with some more polishing done on a hard strop with either aluminum oxide compound ('white rouge') or perhaps some 3-micron diamond paste. Even though it still wasn't quite so hair-popping sharp, the polished 'shoulders' of the convex grind still made for a very aggressive, extremely slick-cutting cardboard slicer. In that capacity, I think the extra wear-resistance of 440C is helpful in reducing dulling by abrasion in heavy, dirty cardboard. That knife works very, very well in that sort of use.
