Yea i have noticed the same, the smaller models have died out. My guess is the smaller all composite models are to expensive for most and those who want to build semi composites isnt a big enough group to keep companies in business long enough to have the desire to come out with newer models.

That said, Ive got the plugs ready for final sanding for a small 60-80N turbine. I just need to get my current commitments done so i can get to sanding on them.
