I did my own and ran it off at Office Depot or a print shop, each booklet fit double sided on one sheet of paper, which was cut and folded together as 4 sections. I trimmed the edges and stapled them, it didn't take all that long. The things are done as black and white anyway. It's just a bit of a hassle to distill things down to fit on the page in small font and give yourself enough edge space to not overlap funny.
Print cost per 'booklet' was 6 cents that way. Plus my time cutting and assembling, but I did them in batches of 25 so it went pretty fast, considering.
