If you end up getting higher cell count lipos in the future, the 120w power limit will just mean it will take longer to charge the batteries instead of the typical ~1hr.

And the only reason for a built-in balancer IMO is so the charger can read each cell. But I prefer an external balancer so I can remove it during charging if I want. And this lets me use one of those little cell voltage monitors if I want to see the voltage. In summary, I personally wouldn't let the absence of a built-in balancer be a deciding factor, but that's just me...
