I have TPM on vinyl, but it is only a double picture disc of the single CD version.
I too am looking for complete scores for AOTC and ROTS, but so far no results. I think GoodMusician has them, but hasn't had the time to upload just yet, which I completely understand.
I came across yet another eBay auction for a 3-disc set of ROTS. He/she is based in Italy.
Here's the pic from the auction:
Of course, I would much rather get them from folks here. :)
