I have checked it out, but the plastic end cap and green tint drove me towards the SC600. No need for the TK35 now, especially when you consider swan's post above. Plus the low on the SC600 is one of my most used levels (coming to bed after the wife, reading at night, checking on the kids without waking them, night time bathroom trips, etc). If you were comparing it to the TK41, the throw on the TK35 isn't even close to the TK41. It is really impressive.
Also, in regards to your post above about the run times on the SC600 in turbo...why would you rather have a light without turbo so that the run times are longer on paper? The light has six levels, some of them programmable. Why would you possibly need to leave it in turbo? Turbo is there for when you need it (not very often). I haven't used my TK21 or TK15 in months because they just don't have the low lows, or the high highs. They're still great lights, but I have other lights now that do it all without any compromises.
