Thank you all for the replies. Yes, it does seem rather expensive when there are other sources in North America that would be more affordable. I know that nothing is truly "drop-in", but these seem closer than a lot of the recent EFD furniture sets that Brian mentions. If I were to go in, it would be a major investment on my behalf. I was planning on taking a scouting trip to the UKicon to see them in person and perhaps trying to return with one to fit myself back in the States.

The no1 Mk3 stocks would probably bring less attention than the No1Mk1s, but how many No1 Mk1s are out there that really need new furniture? I have one which is where all of this began. They don't sell individual stocks unfortunately, so bulk is required. It is something I will ponder in these coming months.
