I've got a CWMK4+ and I love it! not sure how it would work under Amikit as I only used it under AmigaOS4.1u2 but it read my original Amiga floppies fine and also the majority of my old 64 disks too.
Also cool to put two original SID chips in it to get great 'real' stereo SID sounds..I have a 6581 and 8580 in mine
