Would someone please give me a realistic price for a Wiliams Whirlwind? It is listed in "great condition" by the seller on Craigslist, but only has one photo of the translight. I have asked for more photos. Asking price is $1500. If it truly is in good to excellent condition, is this a fair price? I live in the Metro Northeast, where things might be a bit more expensive than the rest of the world. Being new to pinball collecting, are there significant price differences between regions of the dear old USA? Thanks for any insight you can provide.
