You will also know whether (or when) your battery reached 93%-97% - because this is where it would be upon completion of Absorption stage, depending on battery type and brand.
The OP wanted to know whether +$200 monitor would be worth the price, i.e. whether it would make things much easier for him. To me it wouldn't. For the OP - depends on his situation. Size of solar, size of battery, pattern of use.
