Homebrew PCBs

Table Saw or a Sheet Metal Shear are the best ways that I have found.

I have used a Table Saw with a Dry/Wet Diamond blade, Table saw is a 
10" but Diamond blade is a 7 1/4",  also a fine tooth Carbide blade 
should work good but will have a wider Kerf.  For the board sizes you 
listed one of the small bench models should work for you.
If you use your Table Saw to cut PCB material be sure and have a good 
vacuum system on it for dust collection and also put a filter on the 
motor's air intake.  On the motor air intake I used a cloth type 
filter for a shop vac, and be sure and clean it.

Currently I use a Kepro shear that I picked up on Ebay at a good 
price, you can also get a sheet metal shear which is really what the 
Kepro shear is.

Also the Wet tile saws with a diamond blade should work, also guess 
would help keep the dust down.
