What do these go for? I consider selling mine, but I’m not sure
I was bidding on a 104SD last April that was still new in the box. The seller had bought a few of the 104SD’s and had one unopened. I lost the bidding, but it sold for $686. Hope that helps…
you should raffle it off. Jk 
I want one of those. Kind of hard to come by.
The 104Z goes for $729 (1000ms), I would be surprised to see the limited edition SD (1500ms) for less than $800. But I might be wrong…
One sold on E-Bay a while ago for $900 as I recall. 
got mine (inexplicably) for $600 CDN earlier this year.
there might be so few available that there isn’t really a market rate, in the normal sense.
