Showed hubby this set, and sweetie that he is, he told me to go for it - even as I'm waiting on my Toxic and Dolch sets. lol
Presumably the base set is fine for a CM QFR/Max Keyboard Blackbird? Any other space bar sets I should think about adding in case, say, I go for a 60% board in the future?
Not worried about resale value, so at this point, I just went with base and extra arrow keys.
