I have also waited 3 years for stuff to come through, but before Christmas I got the first part of my 3 costume order. I've just been contacted by Dan to the the second part of the order is ready to ship soon.
I know people get angry with the long wait times/lack of communication, but when he's ready, the communication is great- I've had various email conversations and he is one of the nicest guys you'll ever come across, he's also been very generous with some of the deals we made.
I'm not sure how he operates with his business, but if he could sort out customer service, we'd all be wearing DL stuff!
One thing is certain, when you see a DL prop in the flesh, you are looking at something very special. Quality and build are outstanding.
If you don't like long waits and lack of communication, I'd look somewhere else, but if you don't mind, you'll eventually have something very special.
