I got my deluxe and boy is the box huge. I stretched my budget and although the chair is really nice it doesn't make for a great display inside the Detolf. I think I could have skipped and gotten the regular version. Personally, I am big on poses and I prefer the look of Sidious standing instead...
I wired my Vader with an led light using a 5v USB and white led and the 2 belt boxes.
Parts needed:
USB cord
resister
led
wire
heat shrink or electrical tape
I have mines and no issues at all, I don't live in a super humid environment but you should be perfectly fine. For what it is, the figure is good and I am very happy with it although it has some setbacks as mentioned in this thread. Overall I would say get it, it's a great figure!
