since canon recently raised the prices ($525) of the 135SF I'd expect it to go up for used prices sometime. recently, they went for as little as $150 used (I paid $230 new from b&h not that long ago). get one soon. really nice little lens. love mine, works really well with Kenko Pro TC, doesn't focus that poorly, I shoot my kids with field sports with it (not pretending to be a serious sports photog) and it works for what I need. FWIW, I sold my 70-200/4L after comparing it with the 135SF w/wo TC.
Also, a 1.4 TC gets ~190mm on a 135, not on an 85. (oops, on crop, you are right, 85 gets to an equivelant of ~190, the 135 will go to ~215mm no TC, 300mm w/1.4)
