I don't know which model Titan it is (I was given it and it just says "Titan") but I am extremely happy with mine. I've done maybe 700 dives on it and it hasn't even been serviced. I did have a problem with a pinhole in the 2nd stage diaphragm, but as I didn't have a spare I simply mended it with a dab of AquaSeal. 200 dives on it's still fine. I haven't used it in cold water so I can't be sure how it would perform, but I have taken it pretty deep (300') and had no reservations about it. A great regulator.
