Damn! Closet shit is expensive!
When we did the baby's room I used the Martha Stewart closet stuff from Home Depot. It turned out really good and there's a lot of adjustability. This was just a reach in closet so it wasn't too expensive. I've been planning on re-doing the master as well and It's close to a grand just for the parts. It's super easy to install though. You have a metal support that you anchor to the wall and everything hangs off of that.
You can design everything online and pick up at Home Depot which is great. Not sure how complex you can get though with odd shaped closets. Ours is just a basic rectangle closet.
