I did a Google search and found this exchange:
Easiest way to cut PCB's? (with no dust issues)
http://www.diyaudio.com/forums/parts/62929-easiest-way-cut-pcbs-4.html----------
Post:
Tile wet saw. You can get small cheap ones where the blade runs through a water bath, no pump, and eliminates dust. A continuous rim tile blade may not be optimum but a segmented blade or turbo style blade should do well. You can get cheap Chinese variants of these blades that would be fine for circuit board. Look for a blade that states it's for concrete or granite. You can get them cheaply in the 3 to 4 inch size that fits one of these cheap $50 saws.
Response:
Now THAT makes sense.

And since you mentioned Harbor Freight:
4" Tile Saw with Wet Tray

I use the toner transfer method and this thickness works well with my laminator, no mods needed. I also find that my drill bits last longer. At first I was concerned about the board flexing but this was not a problem at all. Give it a try.

Score and snap took forever. I've seen videos of people using 6 or 8" inch sheet metal brakes but never got any feedback when I sent them PMs regarding blade life.
