There are new ignitions available from a company in germany for under 200 shipped, both the bosh and sim style. he 056 is a torque monster series of saws that shine in large wood, I thought I was going to damage the av mounts trying to bog mine with a buried 25" bar, thats how hard I was pulling on it. I will only bring it out if I can drive up to what im going to cut, it's heeaavvy...but when you need to cut huge trees it eats. It also uses the common large mount D25? style bars that all of my other stihl saws use so no need to buy the larger mount bars.
IMO thats a 1,000+ dollar saw to someone looking for a saw that size, for a friend that would sell it back to me if the need arose 3-600 depending what I have into it and its easy to put 400 in parts into one of them.
