Being in a position now to be able to afford a used Nikon D90, What do TP'ers think of refurbished bodies. They are often advertised as having been sent back to Nikon to have put right whatever was wrong, but does it make sense to buy a camera that you know has had a problem, and I'm sure I read somewhere, probably on here, that Nikon don't refurbish items. What do you think, or should I save a bit (or a lot, being on a pension) longer for a new one, and risk there being new ones available.
