Raw Voltage (Austria) are selling LZX, Reverse Landfill and Syntonie Kits alongside built modules and those from afterlife laboratories and brownshoesonly
Exploding Shed (exploding-shed.com - Germany) may also be an option - no video modules yet, but they do seem to be expanding their range - so you never know! almost completely DIY
Thonk (thonk.co.uk - UK) - is also a good idea - especially given brexit - for all the UK residents - they also sell lzx, reverse landfill and syntonie video diy
I think that’s it for european dealers that sell video diy modules
There are a few that sell built modules, but most are ‘by request’ sales - ie we’ll order it for you
I’d also approach at least one dealer in the US - synthcube is the only 1 I know though
good luck!
I’ll probably end up with a full set (including some duplicates) of your modules when they are more easily available in europe, especially if pcb/panel sets are available
