Hi Brad,
I would suggest that you attend a gas show such as "Ohio Gas 2001" held May 4 & 5 in Dayton Ohio. There were 317 spaces sold at "Ohio Gas 2000". The show this year is being held in conjuntion with the "International Antique Advertising & Coin-Op Show". There will be over 500 total spaces. Dealers attend from around the country, and buyers attend from around the world.
I sold and 850 at the show 2 years ago.
For hours and more info the website is:
www.oldgas.com/ohiogas/ or visit the events page on this website for other shows.
Good luck and happy hunting!
Steve
