WO had a bad production run back around 2008/09 and the earlier fluorostars had aluminium cells which might cause issues in very cold temperatures.
In more recent years they switched to a steel cell and the optics are excellent on the samples I've seen. I was the first owner of Alan's FLT132 and it's optics are close to Tak quality, as are the optics on my FLT98.
The only issue I might expect to deal with on a new FLT132 would be adjusting the focuser, which isn't hard to do.
