I'm running a kitaro ct9/ct20 hybrid for almost a year with no issues. Kitaro's g spec units were apparently supplied by turbo tongs, who were set to improve the faults found in the g spec units (oil seals mostly). Never heard from them on this site again since they were soliciting business without proper trader status, but they were making some interesting claims about improved reliability. I am curious to find out if any users of these new hybrids (turbo tongs g specs) can attest to improved build quality/reliability or lack thereof.
