I finished last week the WASP Clone "Jasper"
The pcb and panel is available from https://www.muffwiggler.com/forum/viewtopic.php?t=151625
The Jasper sounds very good, with nice functions like VCO Mixer, addional waveform (enhanced pcb)
total costs are around 300€ (depends on your electronic parts seller for sockets, ICs)
