How much are you willing to spend? The Stages LR is currently a bit over $700. A used single-sided power meter could probably be had for just a couple hundred.
I bought a pedal based PM because I wanted the portability that comes with that - no issues of brake type or different BB standards, plus I can bring just the pedals and go rent a road bike in Utah vs bringing my own. I bought a dual sided because I felt like single sided was too much $$ to spend to still not know what I'm putting out.
Then I injured my feet and ankles, badly, one side worse than the other. Now that I'm mostly recovered, the L/R data is valuable to me.
