We are trialing olympus and pentex---the latest scopes--- we are building a new unit and about to replace all of our scopes, We currently use pentex--have needed alot of repairs--are Olympus any better?? One of our doctors really liked the olympus variable stiffness scope.. Does anyone else have any comments about them and do they break easily??? We are worried about REPAIR and also SERVICE.. We are located in central NY..Thank You!!
