Just as an aside, $24 is a lot for shipping! I don't know how much space 300 switches occupies in loose form but I would imagine it could fit quite nicely in a USPS Flat Rate box.
Regardless, ~$79 is a good price for 3+ keyboards worth of switches and should keep me well occupied. Hell, maybe I'll turn this MX blue Das in to a Gateron Clear Das...
Can't wait to get busy with the iron!
