Man...I hate to price police, but the elephant in the room here is definitely the hacked out Doc Ock scoop. You are asking top dollar for this machine, and I think you will have a hard time. There's just no going back from that kind of modification (without a new playfield), and I think anyone looking to buy a high end pin is going to take one look at that and run. The pics appear to show the clearcoat chipping at the cut line as well...that is likely going to keep getting worse if that's the case. If that is just a reflection, I would be sure to post additional pics showing the clear is ok.
The sad part is, an easy tweak to the bracket and a little drop dead foam would have solved the bounce out issue without busting out a dremel. I honestly think you are going to have to drop the price substantially to get any serious interest unless you replace the playfield. Your best bet may be to strip out all of the mods and sell them separately, then sell the stock game for whatever the market will allow. Just a thought.
Seriously, no offense intended, and I wish you best of luck with the sale. It's a beautiful machine otherwise, so hopefully you will find a buyer who can overlook the playfield modification. Maybe go the craigslist route and hope to find a non-pinhead buyer who will not notice or care?
