I have actually just bought a new Bridge, I see you have the Sony DSC-HX300 listed. I went for the next model up from the 300 with the DSC-H400 and it is very good. 63x Optical zoom and 21mega pixels. Only issue is with the higher zoom, the focus takes slightly longer to fully focus on far away objects.
Another I have is the Fugifilm FinePix S8200 with 40x optical and I love it. Bit dated now, I got it in 2013 but is still an amazing camera. More functions that the Sony DSC-400 and lighter to carry around.
