I bought the TBC-260PF when the transmission head on my 25 year old Stihl SF-66 got a gear tooth chipped, my bad. The Stihl was bullet proof for all the years I had it, but it would bog down when put to heavy task. It also took about 6 pulls to get it started. I probably would have bought another Stihl, but price was really up there, and I had read some very good reviews on Tanaka Power equipment. I also got my Tanaka as a refurb for about $200 off the MSRP, so I bit. The new (Refurb) Tanaka starts on the first pull. This is rare for a 2 cycle engine in my experience, and is probably due to the Tanaka's porting, and the fact that it has a primer bub, which the Stihl did not have. The 260PF is really quiet for a trimmer so that is a nice feature and it has awsome power. It does not bog down it cuts through soft stuff with no problem and I cut down some rose bushes with standard .095 line with no problem at all. As you all know rose stems are tough. One thing that is a little disconcerting about the 260PF is the sound of the clutch engaging and disengaging, which you can really hear because of the High Impact Plastic cowling which this machine has (The Stihl cowling is ALuminum) This particular model is relatively heavy for a string trimmer, but it is a commercial grade machine and not geared to a lightweight homeowner, so if you are one, get a lighter machine or invest in a harness, or support strap of some kind, because the weight will wear you out. I may be overstating this, though, as I am just 5 weeks out of hip replacement surgery, and I tire easily. So far this is a very good machine, but I will update this review as time goes on, because anything can run good for awhile, but only time can tell if youv'e got a winner. I Generally recommend that you use a 32:1 mix instead of the 50:1 mix on two strokes and add a little Marvel Mystery Oil for good measure. Your Two strokes will last forever.
Be safe, and God Bless
