I was big into photography once.
I did a LOT of research into what to buy.
I learned that that my needs would not be met with buying 7000 dollars of
camera bodies and lenses. What if I spent six months or two years and did
NO photography? I ended up with a good Prosumer camera that I still love
but can put down with no guilt.
If your that person. Modular is not for you.
If you decide that your modular is a Spiritual Ham Radio and are going to use
it on a daily basis? Buy in hard and deep. If not, get a Neutron maybe?
