Well if 8 machines makes you you a hoarder, I too have long ago joined that club and went on to join whatever the next level or two is of advanced hoarding. I estimate I have about 50 machines and 1 or 2 that I know is for parts only if I could only find them.
In my "craft" room, I have about 15 at least with the rest scattered throughout the house and we (DH & I) keep bringing them home. I eventually hope to rehome a good portion of them.
