I usually purchase the PPH / PTH (pad-per-hole / plated through hole) boards in a large size and the cut it down to using size. This lowers the over all price. A common product that I have purchased is pictured here:

Vector Circbord

This product may be purchased from various distributors. Here for example note that the P/N 8016 in 6 inch x 9 inch size may be had for about 18.79$US. Here is a Mouser page link.

It is also available from US distributor Newark Electronics for 18.93$US. Here is the Newwark page link. (Beware that the pic on the page is not representative of this particular product).

The UK distributor Farnell also lists this product. The price is listed as 17.94 British Pounds. The Farnell link below shows the page (which is surprisingly equivalent to the US Newark page...maybe Farnell==Newark).

This type of board is also available in larger and smaller sizes too. If you go to the Vector web site and look around you can find the VECTORBORD/CIRCBORD page where all of the standard products are listed. There are some that have the pad-per-hole on one side gridded hole plane on the other side. These typically are not available with the plated-thru-holes.

Often when I cut this stuff I use a guide edge and score down a row of the holes from both sides multiple times with an XACTO or utility knife. This allows the board to be easily snapped apart at the scored hole row. I then use 120 weight wet/dry black grit sanding paper placed grit side up on an nice flat work surface. The rough edge of the Circbord is easily sanded nice and smooth to clean edges. Only a few minutes and one sheet of the grit paper can be used to clean up a prototyping piece that may be say 3" x 4".

Here are a couple of pictures of proto things I've built using this type of board:
