They r pretty darn good and will make anything u need, just send a case over to them. I had a wilson, nice unit, cannot take anything away from them.not me, in fact I am lurking on Ebay looking for a 4th Wilson at the right price in anticipation of building a 6BR later this year. Thirty seconds to trim and chamfer a case is not really a burdensome thing for me. Now before I got the 15 dollar power adapter the hand crank was killing my wrists and I contemplated the Giraud and WFT trimmers
Looking at the Giraud page I do not see an model for 6CM or 6BR even if I wanted to change over. Do they make models other than the ones on this page ?
