I have been fine with the indicator on my regulator.  Yes if the furnace is running day and night the indicator needs to be checked daily.  And check it early enough that you still have time to run out and get propane.  If your schedule is that crazy you may need a third cylinder to swap in and refill next day.  I do far prefer the indicator on my replacement Cavagna regulator.
Costco.com has a good price on 30# cylinder.
I have 2 more full 30# tanks. I am trying to get a kind of accurate handle on approximately how long the tanks last before having to switch to reserve. This way I know when to contact my driver to take me to the propane store. I have to rattle his cage a couple of days ahead of refill time.
