If bidding has already met the reserve and has so 
many days left, I would *NOT* end it! If you were
just selling it to get rid of it that would
be a different story... 

I don't think you have to worry about any nasty
comments in your feedback rating. When people ask
me to end my auctions and I don't want to, I just
tell them sorry, but I can't do it, it's not fair
to everyone else, etc. No one's ever given me
feedback about it. In fact, in a couple cases,
I've agreed to end the auction for them and they
never got back to me, never bid, or anything!
