I have had good luck with about anything that Lowen builds.

I like the high inertia cylinder idea (St Johns Welding makes one too) but it always seemed like by the time I got all the original stuff in the combine worn out it to where I was ready to put in the new cylinder the combine was far enough along in hours that I hated to spend that kind of money on a combine I might sell or trade off if the right deal came along on a new or newer used combine so never did it. The guys that have them seem to really like it.
