What works for rental closet systems?

[Tandi H.]

We are fixing up our first property, a duplex, in a college student/young professional renter part of town.  It's a 2 Bd, 2 Ba about 1000 sq ft.  The bedrooms are pretty generous at over 13x13 each.  Not much storage in the house other than the closets in each bedroom.  One bedroom has two existing closets each about 4' wide, with a single door access to each.

In the second bedroom we are building a new closet along one wall (it didn't have any storage at all).  The closet will be 10' wide, about 31" deep.  Two sets of frosted glass panel sliding doors in front for 8' of access.  My question is what to put into the closet - do we just go with the basic shelf and hanger bar below, or put in a closet maid wire system, or ?  What do renters want and what is durable?
