Hi Yulser,
Personally, I would advocate trying to find an official MB one. I got mine from ebay, where they do appear from time to time, for about £170. In my opinion, much nicer than the windrestrictor one, as it fits the rollover bars precisely, has mesh inserts between the hoops and most importantly, you don't have to drill any holes to fit it. Hence can be fitted and removed in 5 mins. Also worth looking at eBay Germany (try searching "slk windschott") as they are always on there.
Just my twopence worth!
