Possibly taking the price.
Except for the user who told about using a book-sized organ, I might take the price.
In 2003, I was visiting on the Faroe Islands with a group of scouts - far before my love affair with Organs, but back then I had already played the psalms in church for five years. On an island called "Fugloy", the Bird Island - way out in the Atlantic and with an population of ca. 20 - something went awry with the timing and the boat didnt show up on time - and, we were told, might first show up the next day. Which meant we needed something to do. A kind person let us into the charming and absolutely beautifull, little, old church. Up beside the altar was the tiniest pipe organ I have ever seen, with only one stop. Curiously, I asked if I might play it - which was of course allowed.
Sitting there, flipping through the Faroese Hymn Book and playing a few familiar hymns while looking out on the beautifull Atlantic Sea - oh man. Everyone was gripped by the feeling of the moment, and when I intonated a morning psalm, everyone burst out in song. (We were a group of about 10 grownups and a few children)
The biggest organ I have played was the organ in the Church of Saint Mary, in Sønderborg, Denmark. Seeing as I have only played organ (earnestly and willingly) for three months, it was a great thing when I was allowed to sit down at the Three-manual instrument built by Marcussen. My best guess is that it had 50+ stops - I did not count them, but there were two 16" trumpet stops - both of which resembled huge farts (Sorry if I am offending anyone)
