I have the KBP V60MTS-C and V60MTS-Q. I like them both. I have a preference for the feel of the Click version, but if I want to have quiet, the Quiet version is about as quiet as my silenced HHKB.
I also much prefer either of the Matias switches to any Cherry mx switch I have tried, which includes just about all of them (red, black, brown, clear, blue, green).
For caps, I use blank black ABS caps for the modifiers and spacebar, and I harvested dye-sub PBT alphanumeric caps from an IBM 5140 convertible computer keyboard that I bought from eBay. There are a number of vintage Alps keyboards with either doubleshot ABS or dye-sub PBT keycaps. You can search the forums and/or Google to find the specifics.
