I'm quite torn on the issue. I hate to take a heavy loss on the resale ability of my equipment, yet on the other hand, I could look at it from the standpoint that when I'm done with it, I'll give one of my kids a nice camera that will have far more value to them than to the resale market. I mainly want to add the standard 50-200mm zoom (I know, quite pedestrian in comparison to S lenses, but it's what I can afford) so if I bought a used one I probably wouldn't be much further in.
Before all the hubbub I had thought that I might upgrade to the NX500 for a little more low light performance in the next year or so, never really had an NX1 in my sights as I don't see them being within my budget for some time. There is also the thought that if I stick with NX, I can pick up some more lenses and upgrade my camera body for a lot less when the prices drop out, assuming Samsung is truly out without so much as a whimper or a wave, which I'm sure will come when current stocks are sold out.
Overall, here's where I stand.
Used NX300 w/45mm 3d lens + external charger, extra battery, misc accessories - paid $350
Sold the 45mm for $240
30mm f/2 - paid $160
12mm f/2 - paid $260
So I'm in at about $530
Now, here's what I figure I can get for everything
NX300 body with accessories including lightroom - $160
30mm f/2 - $130 (the trim ring on the front of the lens has a little ding in it)
12mm f/2 - $240
so that puts me at around...$530
Not too bad, really, but assuming it all goes to ebay, that takes about a 10% cut out of things so then I'm down to $477 to reinvest in an entirely different system. Let's say hypothetically that in a year the value of everything I have drops 20% from current prices, then I'm looking at $424, and with the 10% ebay cut I would walk away with $382, which is enough for a decent used camera body, sans lenses. Not really what anyone would consider "Getting ahead".
When I break it all down like this and I consider the hassle of trying to sell everything for top dollar and finding good deals on whatever new system I get and trying to get equivalent lenses, it sounds like a major pain in the ass and honestly, $477 isn't going to go too far towards getting equipment that will match what I can do now for what I've already invested. The only advantage would be that new equipment (or new to me) would have more of a future, theoretically.
