I think it all depends on how you are using it. In my reach-in closets with doors that are always closed, or my basement laundry room, Classic is fine (especially if I might slide a door closed while a drawer is open, don't want to chip it). If I were doing a highly visible space or a home office or my main floor laundry which is visible from a few rooms, I'd go Decor.

I love my elfa, have installed it in every home. Need to go get some of the new backrack stuff to add to my garage elfa!

Which closets are you needing it for? (are you likely to need to change the layout?) and are you near an Ikea? We just put in IKEA ALGOT as an alternative to the more expensive Elfa in our children's closets... I haven't decided yet what we'll use on the larger, more likely to change, parent closet.

But, here is an image of my daughter's closet with the Ikea Algot.

We are doing a new build, so I am thinking 5 bedroom closets including master. Foyer and mudroom closets and kitchen pantry. I was thinking of basic setup in 3 bedrooms, so we can expand later. I wanted a nice system, but container store is about 1.5 hours away so it is a little hard to make it before sale ends. Ikea is 1.5 hours away too.

we have our butler's pantry, food pantry, entry closet, and master bedroom closet all in the standard, with platinum finish. The master closet has an island that is 4 shelving units locked together on casters with a hard top. We have a closet, extra wide with huge bi-fold doors fitted as an office in the Decor line. It looks great and functions great too. We only have the wood look work surface in that area. My concern with the decor line is strength on shelves, etc. metal on metal is strong. when you put wood in between the two it weakens it. The dark wood on the office system has to be dusted a lot more too.

I too am building a custom home and the container store sent a complimentary designer to measure my rooms and he quoted 6 closets and pantry including 3D and 2D renderings within 48 hours. I am planning to place my order tomorrow to get the discount.
