I think that depends on how seriously you're measuring power. I have two "double sided" meters (PT hub and quarq crank) and two 4iiii single sided and budget wise, it was better *for me* to get two power meters for two bikes than only get one for one of the two. If that makes sense. 2 sided is better but if you're just a casual rider / trainer it's not a deal breaker IMO.

I was juct thinking the whole 6800 crankset for a double sided output is $999 that is more than double. Power meter City has the 6800 left crank for $300. Some one give me a thought on what they use or if I am going up the tree correct?
I got a 4iiii 6800 for one of my outside bikes and a 4iiii 5800 for my inside bike for less than most double sided meters. That worked out well for me.

You'd think after a few years I'd get a handle on it, but you would be mistaken. If anything, I've gotten worse.
You should get one o' them fancy new garmins... the x30 series has reminders to eat and drink based on your power output.
