I’d try to hit that sweet spot of quality and quantity. Looking at your wishlist I think I’d shoot for;
TSPP
Flash Gordon
Whirlwind
I also like to have a variety of eras on hand. I’d skip the VR pin, they do nothing for me, but that’s just me. If by some chance you have any money left over, I might shoot for a cheaper but fun EM pin like Old Chicago or a small flipper pin like 4 Million BC if you’re not totally opposed to those. That would get you to your ten and be a pretty good variety I think....
