These still available? Any chance you could take some pictures of the backplate so I can get a good idea of the rivet condition?
Bueller hate mentioning this buddy but maybe you'll need to hit Ebay because there are too many bludgers here wanting to pick up your SSKs for nothing whilst some fortunate sellers are getting $400+ each, for some really disgusting looking models.
Get smart and go with the flow, otherwise the shorthairs here will prowl around your classifieds for another few weeks hoping you'll sell your SSK for $100 or less (they will pm you to death, telling you their hard luck stories - all false and fake). Don't get desperate as a seller here on Geekhack because it's not worth it. You have something that 99% of Ebayers desperately want hence why not fill their demand ?
Please re-consider selling them on Ebay if you are looking for serious money to pay your bills, because you won't get it here. Normally I don't get involved in other people's sales but you are my fellow countryman and hate seeing someone being given the shaft. If I hated your guts I would just sit back and crack a tinnie and enjoy the suffering you shall endure trying to sell these babies here. Sometimes you just have to say the truth, I never take advantage of someone who has troubles and that's what most will do here, when it means they can pick up a couple of SSKs for nothing and then they will re-sell your babies for more profit on Ebay themselves. Why allow that to happen?
