I bought this today with my birthday money, and apart from one or two purely practical, and not speculative, problems it's absolutely great.
The first problem was that within seconds of it starting to operate, the eyestalk ceased moving, and although i managed to get it working again, it refuses do do a full sweep, lingering on one side and just going up and down which is fairly aesthetically frustrating.
The second problem is that the gun, eyestalk and plunger are rather weak, I've actually stopped adjusting the gun and plunger because I'm scared that they'll break off. They could easily have been made from the same durable plastic as the rest, which would make them infinitely cooler as well, as a squishy plastic gun just isn't the same as a hard, metallic one.
Aside from those two issues, I'm very happy with it, and I may indeed be buying the gold dalek to keep him company. Then I'll only need two more and I'll have the cult of Skaro...
And no money...
