I would be interested in upgrading the more expensive grinder, seeing how the housing would not get in the way, nor would changing the angle be as difficult. If I took my grinder back to my dealer for an upgrade, would the honor that? I only used to to "attempt" to sharpen one blade. They never told me the housing would get in the way. I specifically asked for the best grinder for me and included what size and brand blades I used.
