NICE! Congrats, man!
I have yet to see the first of either scale in the Black Series pop up in my own local stores but I'm keeping my eyes peeled and they should be on the pegs soon.
Yeah, the R2 is way too small and isn't properly in-scale with the others - I think the company cheaped out on him and used less plastic for whatever reason(s) and still decided to call him a 6" scale droid - but he does look pretty great and comes with a lot of pretty screen-accurate tools and accessories. I'm glad you scored these!
