I was an early adopter as well at $300.00 annually. I still update TurboCad every two or three versions and it costs more than that and does not have CAM. 2D sketches for me are simply much faster in TC.
I find the pricing schemes and transparency with Fusion 360 to be very good to excellent. I am happy to pay that for the return I get from it. It is very good software and getting better every month.
