Which SLR detail set?

So far I know of Scale Motorsport, Studio 27 and Ka models... all 3 make photoetch sets. Which ones are recommended? Any major differences?

I got both the KA Models set and the Crazy modeller for my SLR.I found the Crazy modeller set to be much more useful.You can get it here http://www.hiroboy.com/catalog/product_info.php?products_id=984
And heres my SLR.Hope this helps. Mark
