It is gorgeous. What model is it?
I love old Singer sewing machines. (I have several.) It is really hard for me to pass one up and your machine is in great condition.
I live in Washington State too and most of the time, the treadle machines in that great of condition go for more than what you paid. (At least they go for more on the west side of the mountains. I haven't had very much of a chance to check out the east side.)
