THis is my first year and I'm going to be totally legitimate (taxes, insurance, and uniforms.) I am paying cash for all my equipment, I plan on buying all Stihl hand held power equipment next week. After this purchase all I need is the trailor which I will be getting in about two weeks. I will be a solo operation and want to keep expense down as much as possible for this year. My questions is would you buy the Stihl edger and trimmer or just buy the one that you can add accessories to. I do have a Stihl trimmer that's about three years old that I can use as a backup. What's the pros and cons for the add on accessories?
