Interesting seeing the different thoughts on this guy.
I think the detail on him is excellent, but I was never a fan of that outfit in the movie. That said, he looks great in the displays people have been posting here. If you're a big Joker fan, he makes an interesting addition.
In terms of loads left in warehouses, I guess he's not as popular as the other models. There have been various deals on him lately. You can get him in the UK from places including us for £149.95 if you look around. That's quite a bit cheaper than other Hot Toys 1/6 figures.
Is he worth getting? If you're a fan of Jack Nicholson as the Joker, then sure. But I don't think he'll have the resale value of more popular outfits. Personally, I loved the Heath Ledger DX version. Those flew out the door and deservedly so. Both figures are just as detailed. It just depends which character you preferred. I thought Heath Ledger was the best movie Joker. So dark and twisted. So that's why I leaned more to that figure.
