The original WO FLT110 used
TEC optics, these were hand crafted lenses and were provided with optical testing certification. These were an absolute steal for the price. TMB optics are mass produced, hence cheaper. The same optical lens sets you get in the FLT-132 are in the TMB signature series. I'm sure they're tested but not to the level performed by TEC. If the FLT-132 was to use TEC optics, then you'd probably find it would cost similar to that of the Tak TOA-130F. I guess you pay for what you get in this hobby.
Don't get me wrong, they are still of good quality. Visually, I've also heard similar spectacular comments. However, a good visual scope doesn't necessarily mean its a good astrograph. Depends on your primary use of the instrument.
I would recommend reading some of the essays compiled by Roland Christen from Astrophysics.
http://geogdata.csun.edu/~voltaire/roland/index.html. Roland undoubtedly produces the best refractors available today. His essays touch on coating types and other factors that distinguishes a visual high end refractor to a high end astrograph.
