Anyway, in terms of equipment, I got our ream kerchunker for $200 used. It'll cut 500 sheets of paper.
I got our glue binder for $50 used.
Our laser printer is also a cheap used laser. $50 or so, and we refill the toner ourselves (go with a Brother, so the toner and drum are separate.)
I forgot to include the glue strips in my original cost estimate. I bought a pack of them the first time I did this, I have no idea how much it cost. I haven't needed another pack yet.
I can't imagine they're expensive. I wouldn't have gone with this method if they were.
