Hello,

I'am thinking about changing my 80w glass tube to rf metal tube. Mostly I engraving on plywood and acrylic. The question is it worth it to upgrade or maybe its better to look for new fast laser? Maybe someone already did upgrade like this?

which brand RF tube are you going to choose?
remember to ask them to prepare you the RF tube holder,
it's different from glass tube.

I'am choosing between sino-galvo or synrad 30w

Go have a look at bell laser - they have good-as-new refilled/refurbished Synrad and can give you all the advice and parts you’ll need.

Sino-galvo do not make any laser.
