Sizing a Dehumidifier for 600 sq ft basement

My 50 pint Frigidaire FFAD5033W1 dehumidifier has bit the dust after only three years. Previous GE unit lasted 7. Maybe lost refrigerant? Anyway, I think I need a unit that basically stays on all the time. The basic basement humidity when humid outside is about 55. This unit emptying capacity is 50 pints, but generally empties 2 gallons a day (16pints), and is rated for 4500 sq ft. Seems way to big. I had this on a timer off and on, perhaps that did the unit in.

A smaller 22 pint capacity unit would seem better—or even smaller. Rated for 1500 sq ft 3 fan speeds. Bucket holds 1.7 gallons, about my usual condensate. I usually set humidity at 40% so since that will stay the same, seems smaller than this will result in smaller bucket which I'll have to empty more than once a day..
