I have owned both tlg blades and the cheap chinese blades.
this is what my experience has been with both.

the TLG blades work well in low wind.
they are ready to use right out of the box.
they are quiet.
Terry the owner of TLG has great customer support.

the chinese fiberglass blades
they have poor low wind start up
in good wind 8+ mph they are very fast.
they are not ready to use out of the box.
plan on spending some time sanding painting and balancing them.

if you don't want to carve you own wood blades then you may not want to
mess with the chinese blades.

I believe the host of this Forum do sell finished wood blades.
ask DanB
they have great support for their customers and for the people on this Forum.
