The T-1000 is worth the money, even above retail. Its a DX in all but name (and no PERS).
I still remember when I first got him (I bought 3). I had a 2 weeks off work as I was recovering from a tonsilectomy. Maybe the most fun I've ever had with a figure putting together my different variations - even despite an agonising sore throat.
Yeah the possibilities with that figure is rediculous. Definitely the best deal HT has offered in recent history. I need to get a second "clean" head sculpt for the biker outfit though, I had one but I traded it for some BR Joker stuff.
