Like two threads ago when some mentioned turning new Inferno into him made me get him. For $10 shipped on ebay he was well worth it.
Most of actual transformers from pcc are worth it just as fun little scout classes. Your fun with the actual combiner gimmick will vary though, as some of the better figures make lame torsos and there's no elbows. I think all but the blue car and the Autobot plane are pretty well received. I don't have either of those, but I generally hear bad things. The Dinobots, the boat, the construction equipment ones, the other plane, I think they're all pretty fun.
