You have run into the same problems as most people with a small camera.
The Achilles heel of the small camera continues to be, poor low light performance.
Plus your present camera presents another problem.
It takes excellent pictures (under good conditions).
The current trend in small cameras is adding more megapixels to a too small sensor size.
This results in noise (grain) in the pictures.
So anything you buy will not equal the picture quality you are getting now.
Your best choice right now is the Sony TX1.

It will be marginal better in low light performance.
The picture quality is about as good as your present camera.
Things you can try (even with your present camera):
Do not use flash -- It is too weak to light up anything beyond 11 feet.
If you use flash, the camera is forced to use a shutter speed of 1/40th or 1/60th of a second, which are wrong for action photography.
Use as little zoom as possible.
Your lens loses light as it is zoomed.
Try different mode settings.
Any action setting sounds right but it is probably only right if under daylight conditions.
Try some of the low light or middle of the road mode settings.

My granddaughter is playing basketball in a Upward youth team. the gym she plays in has factory type lighting not flourescent. I have a Sony DSC-T50 but when I tried the high speed shutter there was not enough light, when I used the flash the pictures were a brown color, when I used auto the action pictures were blury. What options do I have? Will consider all types.
Thanks
