Jumped into a camera purchase before I knew what I wanted. Now I do and I don't know if my camera fps is fast enough to get good shots of 5 year olds playing basketball or if I need something faster. The kids won't be speeding down the court because it's their first year so probably a lot of standing around. I already have an 85mm 1.8 lens also the gym is newer so the lights are okay. Should I keep my 600D or upgrade my budget is under $1000 and I have no problem getting refurb.
Basketball pictures from a Canon 550D, the direct predecessor of the Canon 600D.

There is nothing wrong with a 600D, which is essentially identical to the 550D, when it's time to photograph basketball.
All you need is the correct lens, starting with a 70-200mm f/2.8, and noise reduction software. The least expensive fast-focusing 70-200mm f/2.8 lens is a
non-stabilized Sigma 
which was used to create these example images. The
Canon 85mm f/1.8 lens
also has supporters on this forum, but its fixed field of view imposes some limits.
High ISO noise was controlled with
Imagenomic Noiseware
software.
Others will suggest you need to spend several thousand dollars on new equipment, but they will not help you pay for that equipment.
