I love my Charge HR, and they've recently come out with some new colors for normal sizes. The automatic sleep tracking is great, as I'd forget with my flex often enough. I don't even shower with mine, though. It's supposedly safe enough to do it in practice, even if they say not to. I do it just to give my wrist a rest from having it on 23.75 hours/day.
They often go on sale for low 100$, and every now and then sub-100$. Only pay full price if you're wanting a Fitbit.com exclusive color.
