Hey kid, welcome, I'm 17 and also do landscaping. I would reccomend that you upgrade to commercial equipment ASAP. The other stuff just doesn't last and ends up costing you in the long run. I've used crafsman before but it just doesn't last for repeated everyday use like commercial grade equipment does. My first string trimmer, a Craftsman, barely lasted a season. Next i bought a RedMax BCZ2400s commercial string trimmer for $250 and it still runs awesome. Let me know if you have any other question.
