Fast telephoto lens?

I'm looking for a fast telephoto lens for shooting sports in an indoor arena, ignoring Nikon for now which are very expensive I have found these at a glance.

sigma 50-150mm f/2.8 EX DC OS HSM £564
Sigma APO 70-200mm F2.8 EX DG OS HSM £676
Tamron SP AF70-200mm F/2.8 Di LD (IF) Macro £487
Tokina AT-X 535 AF PRO DX AF 50-135mm f/2.8 Lens Nikon £275

Are these all compatible with my D5100 and are they of acceptable quality? IS doesn't matter too much because I can just improvise by using a wall, and the shutter speed will be around 1/500 sec anyway.

Those are all new prices from *******, I have no idea what prices are available second hand.

Yeah, ISO is high, no way to avoid that on APS unfortunately.

I'm gonna use my old 18x bridge camera to figure out what focal length I need, certainly can't afford Nikon's offering though!

After seeing that the 50-150mm is only APS-C, I think I'll have to get the 70-200mm, I don't want loads of vignetting when I upgrade to full frame and try to use the 50-150mm.

The 50-150 is significantly sharper then the 70-200 however, significantly.

Any examples?

Yeah but you lose the benefit of full frame doing that.
