As we have all said "It is only original once!"
I like original, but oddly enough the machine that gets the most use in this house is my restored DP Westy WB-60. Probably because it vends eveything...cans, water and beer.
I think unrestored will hold it's value better than restored and will probably appreciate at a better rate. Seems like a restored machine is like a new car - once you drive it off the lot, you can't get your money out of it.
My wife and I are friends with an older couple who have been collecting and restoring cars for some time now. We recently had a discussion and they are of the opinion that there is a fundamental shift happening where nice originals are what people want now.
Bob, we all know you don't use your machines! You are missing out on the greastest aspect - getting the coldest beer out of your favorite cool machine!
