My wife does photography professionally and loves her Canon 7D, but then you stated that you don’t want a digital camera, so that’s down the drain. (Also, the 7D is on the expensive side).
The best advice I would give you is get a really good flash. The problem with most indoor sports pictures is the delay in waiting for the right light conditions. We had a used Canon before the 7D, and we bought a good ($350) flash for indoor sports pictures. It made all the difference in the world.
As a side note, we were taking mainly Wrestling pictures where the action changes very quickly and you need a good flash to catch the action.
In short, if you go cheap, you get cheap results.
The Canon G-series and probably some other compact digital cameras have the hotshoe on top which can mount the same flashes that are used on the SLRs.
