Usually you can find Craigslist and Backpage type listings by googling something like "Terrco K-star for sale".
I came across one in Phoenix late last year (link attached) though I can't remember what I was looking for now. I almost went over to look at their stock blanks, but figured it wasn't worth the trip if they wouldn't break up the package.
Terrco is a good outfit, I just replaced one spindle and the bearings on my 4x Northstar. Even though the machine is no longer made and I bought it second hand, they were very helpful in selling me replacement parts and offering advice.
