I plan on getting Expedit for storage in the nursery (when I finally get pg). I like how you can get the drawer & cupboard inserts. There's also this website www.panyl.com that sells coloured panels to customise Ikea furniture (incl. expedit), so you can make the drawers & cupboard doors different colours to match other furniture.
If you do a Google image search for Expedit, you'll get heaps of hits. Also try Ikeahackers - people post pics of different Ikea furniture they've modified.
I have about $4000 worth of Ikea furniture stored in my Ikea online shopping list. When I'm ready to buy I'll just email to my nearest Ikea & go pick it up... although may need a couple of trips to get it all
