Got a 400ex on a trade know nothing about it other than it won't start done a compression test on it and only getting a reading of 32psi. Can someone tell me what would cause such low compression?

worn cylinder ?, worn rings ?, bent/broken valves ?. out of time from a bad cam chain ?. piston damage ?.

I was afraid of hearing that, so cost wise what am I looking at roughly?
