I can do $8 a month (plus, I assume $20-ish for the figure?).
But man, I am disgustingly behind. I had the whole series on hold at my friends' comic shop, but when they went out of business, I had to pick & choose what in my hold pile I could afford, and unfortunately, all unpurchased BTAS figures got sacrificed for Minimates.
I only have both Batmans (TAS/TNA), both Robins, Nightwing, TNA Batgirl, TAS Catwoman, TAS Joker, TAS Harley, TNA Two-Face, TNA Scarecrow, TNA Mr. Freeze, and TAS R'as al'Ghul. That's it.
This is a series I wanted to get completed, as these are my preferred designs/interpretations of these characters. I got rid of most of my DCUC collection for these (and unfortunately, the money went to other things...like Minimates).
If these weren't so expensive, or if they'd come out a few years earlier when I still lived with roommates & had more expendable income, I'd be current with every release. Even the big sets.
But if I couldn't afford the GCPD set at retail, I definitely won't be able to afford it at $500+.
