Open-Ended or All Tied Up--What Kind of Ending Do You Like?

Can I say I'm really missing Castle and Hawaii Five-O?  It's going to be a long summer.  At least we have America's Got Talent to get us through.  I didn't think I'd like Howard Stern replacing Piers Morgan because, well, he's Howard Stern, but surprisingly, I've liked him so far.  He seems witty and genuinely interested in the contestants.  And I thought it was funny when he said he was the first American judge on America's Got Talent.  He really is since Howie is Canadian (love you Howie!) And Sharon and Piers were from England.  LOL

Well, as I was lamenting the hiatus of my shows last night, the ending of my book came to me.  A solid ending that I've been thinking about since six o' clock this morning.  (I'm going to write it today I hope so I can pad my Word Count Wednesday totals).  The problem with it is that it's a bit too tidy I think and wraps things up with a big red bow.  I know my publisher likes things somewhat open-ended and some of my readers do, too, so I thought I'd take an informal poll before anything gets written in stone.

Do you like your books to end with all the loose ends tied up and the storyline having a firm ending?  Or do you prefer things to be a bit more open-ended with room for a sequel perhaps or at least using your imagination on how some things turn out in the story?
