I just found and pulled the trigger on two Sentraq S60-X 60% boards (Massdrop link, need account to view), mainly because you can fully reprogram them with TMK and because it allows using an ISO-style return-key. Found it just in time as well, the drop is ending in 10 hours or so. Initially I was thinking about a Poker 3, but the way the programming works feel too restrictive to me, and with TMK I can actually rewrite the whole firmware, so no hurdles no matter what functionality I desire. 60% ISO-style keyboards are really hard to come by, too, this was the perfect board for me. All the other DIY-options I was looking at were way too pricey, and as I wanted to get into small mechanical keyboards for a long time and this was the perfect opportunity. What do you think? Are small keyboards the logical extension of SFF PCs? Or are they too much of a compromise to be worth it? How far would you go? TKL? 75%? 60%? Or even something crazy like 40%? Personally, I think something like the CM Storm QuickFire TK should work for everyone pretty much everyone: And the lowest I can see myself working with effectively is 60%. Everything below would just take too much learning time to be worth it.
