I've been watching the sales forum on the 'cafe and other fora that sell camera equipment and one thing I noticed is that flagship bodies tend to take the biggest hit in the used market! Not only do they get major price hits once a new update or body come out (ex: D2X to D2Xs to D3) once they are replaced, their price significantly drops. Yet with prosumer bodies (D200, D300, etc.) they usually hold their price at a certain threshold. I'm beginning to wonder if it's better to invest in prosumer bodies due to the rate of replacement since cameras are becoming more like computer in that sense? I mean, I shoot for a living, but having to upgrade, sell, rinse and repeat is beginning to get really annoying! I pretty much have all the glass I want and at this point in my career and the way the economy is, I'm beginning to think prosumer bodies are a far better investment, especially in the fast pace of upgrades. Looking back, I've literally have gone through over a dozen camera bodies in the last 5 years! I bet the camera companies are richer than ever before. Ridiculous! Any other others want to chime in? Thanks!
