Yeah, just a couple of repaints. Nothing too exciting, unless you're an avid completist.
I picked up the complete OT set when they came out, since they were an interesting little novelty act. Too bad they cut the line short, and ended it at only 6 figures. But at least they made some decent choices with the 6 they put out...
There's a rather large set of about 12 other figures that look very similar to the Palmtalkers, but are a tad smaller. They were exclusive to Asia I believe, and often come up when searching for Palm Talkers on eBay. I'll see if I can dig up a picture of them...
