My suggestion would to remove all 8 novelty arrow keys. Yes, they are really really nice, but i would much rather have the different novelties, and the arrows with 4 (?) new molds should detract quite a decent bit from the price i suppose.
Another suggestion would be to replace those 8, with just regular maroon arrows as well.
Is both 6u (either one or both) space-bars needed? Especially since you can get those in the space-bar addon kit. Not sure how many actually use those.
So:
-remove 8 novelty arrow
-possible add maroon regular arrow cluster
-remove 6u spacebar(s) since 6u is available in spacebar-kit.
I think we should keep at least one color of the arrows, this is something special from Camping, Camping would be incomplete without those
spliting the novelty is not an option imo. Spliting kits won't help much for the total cost, may even increase it due to MOQ, this is unfair for those who will buy both base and novelty kit.
For the record, according to the pricing I got today, we are looking at $170-180 GB price depends on freight. This is for the kit design in my OP without that 6u spacebar.
I think I'm gonna remove the green arrow novelties and put some spacebars in the spacebar kit, and see if we can get it down to $150-160.
HHKB will stay, no worries.
