There are a few of them available on Ebay in Germany, just have to pay attention to get the actual staggered set. But as I don't need tyres, current prices are not that bad (around 750 to 900 euro for the set) for this region.
I've had the 108s before and I don't understand why these are so popular. They corroded all the time, regardless of how many times I got them refurbished... Got rid of them in the end.
