I have a two year old hc150 that has very little use on it I would guess under 15 hours. Blades are in great shape and are still tight with out ever doing any adjustments. I would like to trade for a Stihl string trimmer. I prefer a FS80/85 that still runs good. I really just need a good engine, so if the shaft or head is bad that is no big deal. If anybody is close and interested let me know and I can email pics.
