We have a vented model and love it. the ventless takes longer to dry. I would also think you may get more moistier from no vented model, I'm not sure if that is true or not.
The combos take at least 2 to 1/2 hours for a load. most time will put a load in before going out and by time where back there washed and dried. your loads are also small so we do use it almost every other day so we don't pile up with dirty cloths. All in all we like not having to go to the laundry mats.
