This is exciting, looking forward to updates. And thank you for being willing and committing to “bucking the trend”. It really is helpful for others to see updates like yours, and hopefully spark a fire on others butts to do cool stuff too.
That said, as much as I back and support SP63 (and I genuinely do and like the guys overall), give yourself mental room for the chance that your build may or may not arrive/be done in as timely a manner as expected. Sounds like you already got the idea that they do a small batch or just one build at a time. Better to be pleasantly surprised than disappointed at a slow-er/ish build completion than expected or discussed. Their stuff is legit, theyve just tended to get backed up for one reason or another at times.
