If you really need MX Red switches that are PCB Mount, It's been stated that Kinesis sells them in packs. Just contact them personally.
I know this is an old comment, but FWIW: Kinesis only sells reds (and maybe browns), typically in quantities of 5-10 per order, to support their own boards. Not that they seem like suspicious people, but when I asked for 170 switches they were curious if I was modding a contoured board, and I wasn't about to lie to them. Oh well
