I've had some good feedback on the Sawmill made by Jonsered. We rent it out every once in a while to the local traditional barn builders and log cabin builders. It cuts some beautiful beams, and can make some pretty nice boards if you are carefull. We use a Jonsered 2095 which makes quick work of the job.

Tom, I'll have to take a look at ours tomorrow, but I think that you can adjust the log on the bed so that a first cut isn't necessary for a straight edge.
Methoss ..You must be talking about the Jonsered 600+...I personally have used that mill alot....I did demos with them all over British Columbia for about a year...I like it very much...it is a bit more setup than the Alaskan mill...or the Granberg Mini Mill...but you can cut anything you want and take out the wane(taper) in the log....and use the chainsaw for any other application you want...with only the removal of a few bolts...I will be getting another that is a for sure....
The Alaskan MkIII mill should be able to do what you need. Instead of setting up your first cut to take a slab off the top to get a flat surface you can set up your slabbing rails and adjust the depth of cut on the mill to slice the log in half giving you a uniform half log. The mill itself can adjust to a cut depth of 13 inches so you would be good up to a pretty big (26" diameter) log. Hope this helps.
Dennis, your right, it is a 600+ mill. I was talking to the boss about it today. He showed me some really nice boards that he cut with it, which came out of some not so nice logs.
