Congratulations on getting back into it! I'm in a similar situation to you - although I hadn't started gathering modules, I'd tracked down enough SIDs to build a full MBSID - though this was before the stereo option was added, so "full" meant 4 SIDs. Life very much got in the way, and now I'm back to building it once I've sorted out exactly what I need based on the BOM that was posted in the forum a while back.
Looking forward to seeing your progress!
