Anyone have the G0454 20" planer from Grizzly. Can't seem to find any reviews of this tool. I am wondering what the differences is between it and the G1033X, besides the indexable spiral cutter. I can order the G0454 and the same spiral cutter head and have it delivered for $200 less than the starting price of the G1033X. It is also about 60lbs heavier and has built in casters. What am I missing here? Any insight will be helpful.
