I print my own tokens on 1" circular labels and stick them on 1" washers. Works great and the tokens have a nice "heft" to them. There's a site that sells labels by the sheet for a reasonable price. They also have sheets with 2", 3" and 4" labels for the bigger monsters, though you'll have a harder time finding bigger washers. I use wooden disks purchased at my local craft store for these. Google "labels by the sheet" to find the site if your interested. (Note, I have no affiliation with the site other than using their products.)
