When I was looking for a motor once, I discovered it would have been cheaper to buy one of those pillar drills, remove the motor and throw the bits in the scrap bin.
Prices have risen since, but it may be cheapest to replace the whole thing.
Compare:
Drill press at £80
Slightly more powerful motor at £83

<edit> if it hasn't burnt out, you probably only need to replace the start/run cap[acitor under a shroud on the side of the motor. Bargains! Much cheapness!
