trust my pricing, if anything, its a little high since I last updated it...I have been tracking sales on eBay for years now and there is a big difference between what people ASK for a table and what they actually sell for...my numbers reflect actual sale prices not the silly and often insulting prices I see people post on eBay and CL. These people are either totally ignorant or they are trying to rip people off...I have seen people ask more money for a Brown Marble than you would pay for a brand new coin op purchased today and that is true of every table from brown forward. I have even seen people ask $1100-$1200 for a 5-10 year old Cyclone.
I have someone I play with regularly, new back to the game, found a current coin op model for $700, I have seen 8 different Grey's sell for $400 in the last year...these are not all on eBay most were through CL with people i was helping when they were buying. I can give you other anicdotal stories of $150-$250 Brown Marbles. As was pointed out, the key is waiting and searching the largest circle you can, getting your money ready, and making the offers. Learn what you are looking for while you search, know what to ask-what is a deal killer, what can be fixed or updated and how much it costs and how you can use that to negociate your price.
or spend the money once and buy new...if you do that, buy Fireball coin op...its a lot of money compared to used Tor coin ops but you will never regret it...but, I understand not everyone can do that but for those who can, its the best choice
good luck in your search and as xiek376 said, be patient, your deal will come...just keep asking and offering like they did, keep your search as wide as possible, and your day will come
contact me any time, I will answer questions and help in any way I can
