I wish! It’s apparently very cheap when buying used.
As for the KS, yeah it’s a bit confusing. For some of the 3rd party designs you might need additional parts, but I’m sure we’ll get those details closer to release. I also missed out on the Early Bird even though I was there when it launched but the difference was only €6 so no big deal. I did pledge for 5 additional kits though, I’m sure I’ll be able to use them haha (either selling, giving away or to have multiple models).
