I don’t normally build from kits, but about 6 months ago I bought the Jeannie boards from Tube Ohm. Basically it’s an 8 voice poly VST with an additional effects board. Most of the SMD is already soldered so you just have to gather the rest of the components from the BOM and solder one 24 pin SMD chip to the effects board. Still waiting on some of the more obscure parts that I don’t have in stock, but built it in about 4 hours. Rolf the creator is still developing new functionality for it so it seems well supported.
