Warbot is probably my favorite 3rd Party TF. I sold mine off a while ago and I have him siting in my cart with a very itchy trigger finger at the moment. He also went up in price while he was out of production for a while and this new run is priced higher than the last.
He's got die-cast parts. He's got a nice heft to him and I like all three modes, particularly the armored car, but you'll probably want to keep him in bot mode. He's got great G1 "chunk" but a pretty intricate transformation.
I would say he's definitely worth it and this is a great time to get him for around his original price.
This is the video that made me pull the trigger (reviewer really enjoys his nerd-snark but I like how he shows off the figures. I also have a high tolerance for nerd-snark when it's not
