Hey fellas, I have a question about the Stihl FS90 trimmer. I'm looking to buy one and went and looked at them at 2 different dealers. I was under the assumption that the FS90 had a interchangeable gear box and accessories could be used with it, like cultivator, broom, etc. BUT, both dealers said, oh no, you need the "Kombi" unit for the interchangeable add on implements. The "Kombi" FS90 is $299 but I would have to buy the string trimmer head unit for another $89. The regular FS90 is $299 but is ready to trim. The Stihl brochure book from one of the dealers clearly shows attachments for the regular FS90 model and also for the "Kombi". Am I missing something or did Stihl change things? I'm confused. I'd like to but the regular FS90 and IF I need attachments I can. But If I can't ever add them, then maybe it's the Kombi unit. And help would be greatly appreciated!
