I was in the same situation as you looking for new lugs to replace my Work RS-R 'Red' (so Pink lol) ones that I had to drill out, and I also looked at the Volk ones. It wasn't the high price that turned me off them though, it was reports while reading reviews that over time the hex portion of the caps will strip out, and the socket that comes with them to remove the nut will start to round off too making removing them impossible.
I ended up going with the Project Kics R40 Revo's and ordering the red caps for those. Seems like they are pretty universally the most loved tuner nuts for strength, durability and looks. Same 2-piece floating collar design too. And you can get them from garage16.ca which is local to you
