This auction shocks me. It's over $800 now. All we have here is a different colored plastic with some blue caps. It's later model SSK made by Lexmark, so it will not have as thick of a plate as older Model M's, and, consequently, a worse feel than earlier Model M's.
Then we have a nice bolt mod SSK available on Ebay for $325 flat, lower than the recent selling price, from a guy that loves Model's M, has done plenty of bolt mods, cleans them meticulously, offers a return period, and stands behind his product. It's a great board. You could buy it and paint the darn thing to the color of your choice.
