I have somewhere around 30 in various stages of refurbing. Unfortunately, most of them are situated such that I can't pull them out and sew with them or they are waiting for me to replace a part or clean them up or refurb the cabinet, etc.
I have five or six which I sew with all the time, even with all these choices. I am thinning out the herd so that I can keep all my machines working. It's not good for them to just sit and look pretty. They like to be working. :)
