I don't think there are enough low level items in the game to make them all unique. You need to get a duplicate every once in a while.
Like I said earlier, it would be nice if completely useless items, like the stone mace, are less common than more useful ones, like accessories.
But how difficult would it be for SD to increase the number of low level items, thus decreasing repetition?
It would be pretty easy low hanging fruit IMO. They don't have to be very creative either. For exmple, a variety of low level swords or staffs each with a different minor benefit. One would have +5% magic resistence, another might have ignore 20% of opponents defense, another might have +2 dodge, etc, etc.
If I can create stuff by adding/altering the xml files, it should be a very easy thing for SD to do.
