Hi, I have been collecting these machines for over 10 years myself. I have about decided that the "buying price guide" that I have is way off...
I am happy to see new collectors coming on eBay and buying machines. I have been an eBayer since 99......so I have seen a few new names buying these old machines.... I myself have some machines that I probably paid too much for.....But I believe another 10 years down the road will prove that I didn't.....Where I live....here in NW Arkansas....if you listed a Columbus model A in the local paper for $300.00.....I doubt you would get a call......But you would more than likely sell it on ebay in 7 days. I had one dealer from California tell me that eBay was ruining all the good shows.......But I had to remind him that all of us could not attend the shows and that ebay lets us look all over the country......and not have any traveling expenses.......Several of my machines have came from an eBay auction.....And I am glad I was able to bid and win the ones I have...
Without the internet, I would never have known they existed....
Good luck with your ventures!!!! And if you have a neat Old machine for sale, Drop me a line..
