Panasonic FZ100 Bridge camera

I recently bought this camera and after a few trips out I am getting some very acceptable pictures. Apart from the normal family photos my main interest is wildlife, especially birds. The optical zoom on this model is 24x -with a little tweaking this can be slightly extended. Accessories listed include a convertor and lense and at a price of approx150+ I would appreciate advice from someone who has used this kit with this camera before I invest. Are there any problems and is there much extra weight and what about the quality of photos and what would the acceptable range be. I know a DSLR might be the answer but due to medical problems I like to travel as light as possible and spend more time in the fields rather than hides. Any help please. TWC.
