Signature Plastics now has a
custom order page where you can place orders for up to 50 sets of custom keys.
Here are the colors that they currently have available:
Pricing looks pretty reasonable I just need to ask and find out if you order 100 or more sets if it gets cheaper, but I'm already pretty sure the answer is yes.
They will have base sets of 54 keys, modifier sets of 33 keys, iso add-on, and 17 key tenkey add-on.
I assume "1st shot" would be the legend color and "2nd shot" would be the key color.
Stuff like tsangan kit will most likely need to be done separate still, but this greatly simplifies the orders. I wonder if this will start new group buys of "First 50 orders get a set". Let the fun begin.
