Having more or less decided on going for the D70s as the camera for my first adventure into dSLR, I've been thinking about whether I should save myself a bit of money by going for a second-hand D70/D70s (nowhere seems to stock new D70 any more), or play it safe and get a new D70s. Two questions: -Firstly, given that ebay has an abundance of D70 cameras, but less D70s, would I be missing out on much by not getting the revised model of the camera? -Secondly, how risky is second-hand dSLR camera buying over ebay? If I get a duff camera, am I pretty much screwed? Has anyone had any bad experiences before? Bear in mind that getting a second-hand camera could save me just under £200! (which could go towards some nice new lense...) Thanks!
