if you're going to cheap out then why not go 5/8 or 1/2 and brace it. I would say its the same idea.

MDF is cheap //content.invisioncic.com/y282845/emoticons/confused.gif.e820e0216602db4765798ac39d28caa9.gif

Look into AraucoPly. Light sturdy and cheap.

Was going to do my wall in it but they were out of stock so I used MDF..

Box I did before my wall was birch. I loved it but it was too expensive to do my wall with it.
