camera recommendation for sequence shots?

[WTF?]

my mum's going to get me a good dSLR for christmas at the end of year 10 if im still into photography (which i most probably will be), but the thing is, i cant decide on what camera would be good for what i want to do. i want to be a skateboard photographer, which involves having a camera that can do fast sequence shots to get the details of the tricks, so my question is, do you guys have any reccomendations for cameras that can do high speed sequence shots, that is relativley low priced?
thanks.
