keithhohNot sure Jack will provide that option but if he did it would be on the OLKB website. To my knowledge, even on the website of past drops/years, they have ONLY been in KIT form but I know Jack HAS DONE earlier sales of him doing the soldering.. He has(had) a video out there doing 200+ boards :)
keithhohNo preassembled option. It's not that many switches, and nothing all that crazy. I'm confident you'll be able it pick it up. The last board I made was my first time ever soldering and it worked out fine.
keithhohi taught my wife, a self admitted clutz and terrible learner, with no hand eye coordination. to solder. It took a few switches to get it, and by the second row on her first KB she was a pro! Any one can do it as long as you still have hand/muscle control.
