Thanks for the thoughtful response Rob; that was a very helpful post for me and I went through The Pinball Compendium Volume II and Volume III three this evening (thanks to PinballHelp for suggesting I get that trilogy of books) and did put together a list as you suggested.
I think I will pick from among the following:
Paragon
Gorgar
Black Knight (1980)
Xenon
Flash Gordon
Centaur
Black Hole
Catacomb
Strange Science (87)
Dungeons & Dragons (87)
Both Strange Science and D&D were a little newer then I had in mind but I've always wanted a D&D and Strange Science certainly meets the artwork. Ultimately, since I am really looking to bling this sucker out as much a high end restorer is able/willing to do, I think that will likely eliminate Flash Gordon and Dungeons & Dragons from the list as it is harder to see how the bling on those two would work.
A mirrored backglass is also an absolute must so if any of the above titles I listed do not have one let me know and it is out of consideration (I want this backglass to freaking pop!). Good base sounds are also important (that is really why Gorgar is so high, that heart beat of Gorgar is awesome to hear).
I think you are right Rob in what I need to do is talk to some restorers. I had hoped to get a few more references in this thread than I have so far. Since HEP is not taking on any more projects this year the only other high end restorer I can think of is Keller. I will give him a call late next week; I see from his website he also sources the games so that is extremely conveinant. I was going to buy AC/DC Premium but my buddy who lives a couple blocks from me now has one so I am going to divert those funds to this project.
As you say Rob, I have absolutely zero expectation of getting my money out of whatever machine I do; it is really just going to be a show piece that I will keep in my office. It won't be placed with my other machines.
Anyway, if anyone thinks I've left off a machine I should really consider please let me know. Also, if anyone has a particular reason why one on my list may be better to bling out then another please let me know and give me some ideas.
Thanks for the post in the thread guys. This is going to be a fun project for me and I plan to keep everyone posted as it develops (even if the restore takes a long time).
