If any volume, then the tri trimmer types are the only way to go.
The Gerard Tri Trim can be chucked up in a drill and clamped in a vice and you have a motorized Gerard with a solid base (I have three of those)
My only other one is a Trim it II as Gerard does not make 7.5 Swiss in the Tri Trimmer type.
I can trim 300 cases in 30 minutes with those, corded drill clamped upside down in a vice.
