A kit that will include:
Top/Bottom Aluminum Case
Brass weight
Plate in Brass/Aluminum
Logo in Brass/Aluminum
QMK PCB
will run you $420.
Shipping in the US should be ~$20-25 depending on location (shipped from US-TX). From my experience with the QXP group buy, most international shipping is ~$50-60.
