I purchased my tan 301A from Ebay. The person I purchased it from maintained it extremely well and it sews like a dream. The price was $200, but I did get free shipping. I did have to purchase some additional feet for it, but considering how wonderful it sews, did not think that was a major cost. Once you find one you will LOVE it. Just a personal note....does color really make a difference? Why pass up one that is a different color and sews great?
Best of luck in you search.
