We use our school district's print shop... they are MUCH less than other printing services. They have the saddle stapler, GBC bindings and other features. They also have a contract with their copy services people that will give us great prices on things they don't have on site... like spiral binding.
Unless you are going to use the binding more than several times a year, it may not be a good use of resources (money, storage space, maintenance, retraining next users, etc.).
We are looking into purchasing a folding & stapling booklet maker for our elementary school PTA. We have been paying for copy shops to make booklets for us several times a year, and used to have our directory spiral bound for $1 a copy.
Now we're looking at moving to a stapled directory book, and getting a machine to make our own booklets.
I'm looking for input from anyone who has owned or operated a tabletop booklet maker. Did you use manual, electric or a combo machine? What were good and bad things about the machines you've used?
