The main thing you need is a bright lens.
A zoom lens rated at f/2.8 would be a good choice.
The lower the number ... the brighter the lens.
Canon and Nikon have the largest selection of lenses.
Any of their entry level cameras will do fine.
Just remember, you MUST turn-off the flash.

I'm looking for an entry level SLR digital camera best for shooting indoors(basketball) for under $1000.
