Seems that serious lens centering issues with "TOAs" and its "first run" was:
"There is some misunderstanding about the earlier model of TOA-130. At the first stage of our introduction of TOA-130, we have received many claims for almost all TOA-130 OTA from our USA dealer that there was astigmatism on TOA-130, and according to their expectation, the astigmatism was caused by the lens cell.
After receiving this claim from USA, our technicians have checked and investigated in details spending a lot of time and finally found that the USA dealer has used inaccurate collimation tools and they have visited Japan, and have acknowledged their misjudgment. This is the real story and we confirm that there was no problem at all on the lens cell of TOA-130 from the beginning. If you heard such claim from somebody, it is a definitely rumor, and we have never changed nor modified the lens cell of TOA-130 since our first introduction till now." (Takahashi Japan)
Okay I can believe that.
The same, however, cannot be said for the first run of Sky 90s, which were revised to the Sky 90 II. The point is that lens cells are a lot more critical with air-spaced designs.
