Well Im bucking the Trend here.
I had a Trend T9 inverted in my table for 18 years before it gave up the ghost.
No problems except collet changes and used extensively on a weekly basis.
Changed to the T8 below table and can't fault it. Works great through the router plate. Only thing I changed was the height adjuster to a crank just to make moving the router up and down easier/quicker.
I cant for the life of me see the advantage of a router lift especially at the prices they want for them.
Ive always had my router table hinged at the back so it can be lifted off the table and a stay used to support it. This way you can change collets and make height adjustments quite easily.
As for Trend quality.
Any company bulk buying routers and having problems would certainly have a replacement/ repair as part of their contract. Besides they would have changed brands had the issues been so bad.
But its like cars, and asking, is this model any good.
Depends who you ask?
All I can contribute is that for 30 years plus Ive used most router types. For under table you need 1/2 collet models that give you the power to cope with their use and the ability to hold those thicker dia cutter for stability and coping with thick material.
As a final word Trend do look after their customers and if I were you Id be on to their technical department to answer any questions you have.
