Returning my Fz100

I love my camera. Great speed and features. Really its amazing. However Low light pictures are nothing like the Fz38 Fz18 or fz20 . Reason I am taking it back is dead pixel on screen. That's minor however still not ideal. Noise on evening pic's just hurts too much. I really don't know what camera to get next. Might buy another Fz38 as I sold mine already. But will miss many many features of my current Fz100. At least 30% of my pics are at night and there is nothing worse than getting home putting it on the pc and finding that none of them are any good.
