There's lots to check on a second hand DSLR, but if the shutter count is reasonably low, there's no hot/dead pixels and it looks like it's been well looked after, I'd probably go for second hand, having bought a 'lower in the range' new one and not had the reddies for better glass.

Shoot a white wall, and take a shot with the lens cap on. Study image for any pixels that might show up.

Might be worth checking online to see if there's a local online forum that you could buy from, where you can see the goods properly first, as opposed to ebay.
