I've used a T2i and a 60D for figure skating. Both can handle the higher ISO, but both will have theire fair share of OOF shots do to relatively slow focus tracking. The T2i has a very slow burst mode and buffer. The buffer on the 60D is better for JPEGs, but RAW will fill up if you're not careful.
Consider Canon's refurb store. I saved a bunch last year with my 7D from there.
Of the crop bodies currently available, I think your choice will narrow down to two options.
1. T4i -- With Digic 5, has the best high ISO noise reduction for JPEGs. RAW images should be very similar. Also offers auto-focus for video. However, this is NOT a high action body. Only 5fps and a RAW buffer of only 6 shots. You can get excited about the action on the ice, fire lots of shots in a hurry (not all in burst), only to have a full buffer when the puck enters the net. But, the price is good. (The new T5i is essentually the same camera with minor updates.)http://shop.usa.canon.com/webapp/wcs/stores/servlet/product_10051_10051_320718_-1
2. 7D -- The best sports crop Canon makes. Compared to the T-series and the xxD, it's focus system is amazing and a great match for the 70-200. I bought my 70-200 when I had a 60D and was frustrated with roughly 20% OOF of figure skating shots. 20% doesn't sound bad, but if your key moments are among the 20%, it's terrible. For me, the 60D held me back from the full potentual of the 70-200. As for the buffer -- nothing to worry about (I use use Transcend 600x cards). 8fps is a nice bonus. Slower burst rates are often useless after the second shot. For figure skating, I prefer shutter speeds between 1/500 and 1/800 at f2.8. I routinely shoot at ISO 1600- 3200. You will get noise, but Lightroom 4 does a great job at cleaning it up.http://shop.usa.canon.com/webapp/wcs/stores/servlet/product_10051_10051_260463_-1
