This Sm has been up for sale a couple of times on ebay and like rotty guy I nearly grabbed it as well but I bought my Ironman instead.
As far as I know it is a stock standard pro model huo aus delivered with very few plays in excellent condition.
Best of luck if you are thinking of grabbing it, It is a very nice spidey, if I had the cash I would grab it myslef as this is the only other pin I am chasing.
Pity stern has not made more pins of the calibre of sm and im, they were the best pins stern made for mine by a mile....imo they have lost the plot BIG TIME with these new models that have  3 or more different versions that are designed to get as much cash as possible for stern and have little to do with the pinball buying public as a whole and the endurance of the hobby in general.
