I currently have a Deluxe JustaRack and have owned the regular version
as others have said, the deluxe has the thicker rounded shelves, each shelve is very heavy, the rods are thicker in the deluxe.
I think my basic rack had 3/4 inch shelves and were sort of squared/rectangled on the edges.
the deluxe is a very good rack, i beleive a 5 shelf version used to sell for $600
if you are looking at the standard one, it would be a fair choice for a basic system, and you could do much better, but if it is the Deluxe one, in my opinion, it would be harder to do much better at its price point
