I was looking at a Ti15 to pair with my CSX and Centrotec set. Before the purchase I decided to research a little here on FOG. I found a few people that really liked the Ti15 and several that had concerns. I am a hobbyist so no real need. A few people here suggested I look at the T18 +3 as an alternative to the Ti15. I ended up with the T18 +3 and its a great for me.
