I bought a White Rotary machine in a beautiful cabinet - machine was neat too - no decals - all the decorations were cast - have only seen one other like it - paid $40! I would probably have paid more for it since it was LOVE AT FIRST SIGHT - it needs a rubber wheelie thingi for it to run quietly - on the hunt!
I paid $125 for a FW at a yard sale a few years back and $250 for a FW that my husband's cousin found for me in California - she shipped it to me around Christmas and it got delivered to the wrong address - thank goodness the lady was honest and my phone number was on the label - she called me and apologized because her kids had already opened it thinking it was Christmas presents! We both had a good laugh when I picked up my machine.
I go to garage sales and estate sales and always keep an eye on the online places like craigslist and shopgoodwill.com - you never know when you will score a bargain.
