Most collectors I know have either really cut back or stopped buying altogether.
I certainly have. I wanted to have each of the Doctors. Well, I have them. I wanted to have a few of my favorite companions, but with the exception of Leela, they are only being released in multi-packs with others I don't want. Peri and Sil? Seriously?
I think I can actually pinpoint the moment when my collector buzz switched off. It was when someone here posted pictures of the Peri/Sil set, with Sil removed from his base, and it was a giant brown spot, a turd left behind. I sort of woke up then and decided I'd had enough. The only figure I've bought since then is an Eighth Doctor I picked up on eBay.
I was interested in picking up a Leela figure since it was being sold on its own, until I saw pix of that one ... the quality control is terrible. The arm was falling off, the joints weren't done well, the paint job looked like something a psychotic drugged-up drag queen did halfway through a bender.
At least we've still got the sonic screwdrivers.
