Welcome!
I'm not about to try to list all the machines I've bought LOL!! They are addicting!
My "first" was a 66 red eye in a beat up cabinet for $25 at auction. It sat as an end table (no aquarium though) for many years until I was considering finding a machine to sew rabbit hides on - and found many used these old machines, and I already had one! In the process of fixing it up - got looking and bought a really nice one, then a nicer cabinet, then I needed a 201, then found a different 66, and then . . .
But I was doing OK until I wandered away from Singers . . .
My husband also likes the machines, and does most of the repairs (just re-timed my long arm), and he likes the foreign machines. Between the two of us, we're somewhere around 120-130 mark.
