I too have a little black speck of dust on my D40, either I've gotten used to it or it went away, since I haven't noticed it until I came across this thread. The speck of dust is only visible went pointing at a white wall anyways.
Congrats on the upgrade! The D60 seems cool, a sensor cleaner seems nice, if it does its job. I never take my lens out anyways(Nikkor AF-S 18-200mm), I guess I don't really need one.
Sorry chiefroastbeef, if it is within the return period I would take It back to where you got it. And yeah the manager looked like he was going to ***** his pants. I forgot to mention that after I got the new D60, I asked for the manager's name and employee number, because I said that I wanted to call corporate HQ to file a complaint against him. I haven't done nor am I planning on it, I just wanted him to fret all night. I know, that was mean of me.
