Thats the method I use. Works very well but you need to use a metal
ruler (I use a thick metal square, something like this
<http://www.harborfreight.com/cpi/ctaf/displayitem.taf?Itemnumber=9541>
) and you need to match your cuts on both sides exactly. If they don't
match perfect, thats when you get uneven edges.
Put the portion of the board to keep under the ruler while holding it
down and snap the excess upwards. I get very clean cuts that way. Oh,
also get yourself a rubber cutting mat (like this one
<http://www.modelkit-builder.com/wp-content/uploads/2009/01/cutting-mat.\

counters. :)
