I have a Bosch shear in either 6 or 8 gage (not looking at it right now and memory isn't that great). Good tool, and it has its purpose, but for a nicely finished edge with less prep time I'd give the edge to my old Hypertherm 900. Actually for 10 ga. I have a couple of cheap Harbor Freight Skil type metal cutting saws that beat both for a nice precision edge...but they are an ungodly mess to operate throwing metal chips hither and yon! If cutting other than an absolutely straight line the Bosch can be more than a handful to keep under control.
