What is the difference between a TA60 and a TA61 Turbo?

Has anyone had a problems with there TA61?

Because mine took a **** on me the shaft got loose and the blades rubbed on the housing.

No problems here. Mine's an old John Craig unit. Its been working flawlessly for 3 years for me and I bought it used.
