You have found yourself the buy of a lifetime. I bought my #1+ in Oct. 1998 for $3600. A few years ago I traded it in for a Designer SE so I could use larger embroidery hoops.
I wish now that I had kept it as a backup. It was a wonderful machine, easy to use, and problem free.
Give yourself some time to learn how to use it and I'm sure you will love it more and more.
Here is a link to a stitch chart for your machine. It will show you all of the utility and decorative stitches your new machine can do. This chart is 22 pages long...woohoo!
