I recently bought a 1" button/badge maker off of ebay and I'm having a blast with it.
Along with the button making supplies, it came with a crimp die and just a few flat backs (which I've used to make magnets). I would love to get more magnet parts - I've found one site so far that sells them but was wondering where other people get them. I'm talking about the specific supplies to make magnets with this machine.
Also, if anyone wants to do a button or magnet trade, let me know.
I've set up a livejournal for my buttony stuff at tiarabuttons.livejournal.com.
Oh, and I had a great experience with the ebay seller - if you're looking for a button machine, I'm happy to message you with the seller's name. It cost about $260 including shipping for the machine, the circle punch, 1,000 parts, the die, and the flat backs/a few other button parts.
