My experience in spending 2 years looking for an R22 to use as a simulator was..... nothing doing. If it is timed-out, then the price is high because it can be reconditioned.
I looked at crash-damaged, and found that I couldn't get something sensible - too "bent" to be of use.
I did consider a Wessex - had the opportunity to acquire a complete machine for £5k, but it is too big.
Eventually I got hold of a crashed "self-built" fixed-wing, chopped the wings off and made a trailer for it. With the addition of steps, and a 12v battery to run the lights / instruments, it now goes around school fairs and other events raising money for the school or event organiser.
