KRA I thought you were a collector well before you bought that machine.
It's easy to justify the necessity of the first 3 or 4 machines because of different functions you can have each machine perform but after that "necessary" kind of flies out the window.
I think the world would be a far more boring and sad place to be if we only did what was necessary. 8 or 9 machines is only the tip of the iceberg. I think between my daughter and I, we have around 20 machines at the moment and I consider myself strictly small time when it comes to collections.
