As of now: RSI Constellation, RSI Aurora, Origin 300i, Anvil Aerospace Hornet, MISC Freelancer, Drake Cutlass, Vanduul Fighter, several skins & the hardback Squadron 42 manual. All in all over $1100 with no regrets. Due to the continuing upgrade path I'm quite sure I'll get the other five ships (another $880) execpt of course the Idris Corvette (shame - I'm hocked up in another project limiting my ressources).
Main reason for spending that much: I really believe that Chris Roberts can make an exceptional game, my deeply rooted affection for space sim games (X-Wing, TIE Fighter, X-Wing: Alliance, Starlancer, Freelancer & of course all Wing Commander games) & my collector's OCD
On a semi related note - which skins am I missing when I've got: You Got Our Backs, Exploration Skin, Military Skin, Blackbeard Stealth Skin and False Colors Skin?
