I have one of the old Kepro shears, has a 12" blade, it has a pretty good angle on the blade. Boards that I normally cut are upto 1/16" FR-4 upto 8" wide. I do have some trouble with nonstraight cuts. I have to really hold the board, need to make some kind of clamp to hold it in place better would make it easier to use. I got it used and it did not have a handle for it. Made one from some 1/2" steel rod, made it longer so it has good leverage to cut.
The other method that I like to use is a bench size table saw with a Wet/Dry Diamond blade in it and Vac system to collect the dust. Got straighter more consistant cuts with the table saw setup. The dust does take its toll on the motor. Putting a Filter around the motor helped. Think I needed to refine the Dust Collection and filtering for the motor. A wet Tile saw should work good too, water would keep the dust down.
