If you aren't after something cheap I have something a bit special you might be interested in. I've been working on a replica A600 2D motherboard for a few years now. The money raised will be put into a CD32 rev4 replica next.
I scanned and traced a rev 2D pcb using Kicad, fixed a couple of minor things that for some reason weren't connected on original boards but that's all as I wanted to keep it original. The major parts are taken from the scanned board, AVX MLCC, Panasonic resistors, Panasonic 0.1% resistors (thin film) in audio path for high accuracy/better balance and theoretically less noise. Panasonic hybrid SMD capacitors and solid polymer through holes. Rohm RGB encoder that is somewhere in between CXA1645 and CXA2075. Basically no expense spared.
