Do you think they would do space bars caps lock etc?
I have bought caps and resisters from them in the past.
Shipping is about £800 per order. (well £10)
Or it was.
Nah they are just a general electronics company so they are just selling keycaps to people who build custom/bespoke systems for other people and often caps lock/spacebars are often not required.
Also I notice on many of my keyboards that every keyboard have very slight differences in the space bar length, windows, ctrl and alt also vary from keyboard to keyboard.
Anyway I was considering getting 85 single red blank key caps for my G80-3000 to make it look really bespoke and give the impression of that hand painted hhkb i saw for thousands of £$ but if it costs £800 to ship its not worth it.
RS also sell cherry switches ML and MX switches but to be honest its cheaper to buy a brand new mx/ml keyboard and havest the switches and keycaps than to buy individual keys at their prices, unless you are only replacing a few keys
For US residents its probably cheaper to buy from X-Keys instead of RS anyway, but I think buying a few to check for compatibility. The best option though is to just buy the same keyboard in a different colour.
