The new Hap 2 bodies with the improved shutters are the best bet.
my experience is $1500 CAD for a new shutter after 30000 clicks, and a 7-8 week repair turn around on a Generation one body.
If the body is inexpensive, it may be a good deal, but you should expect a repair around 25000 as that is the new body warranty cut off on the first generation bodies.
