I just placed an order for the Dolle shelf last night. When It arrives and I get it up, I'll post pics and my thoughts.It seems to be a perfect fit according to the dimensions.
Thanks for all of the recommendations, I was just looking for something that was ready to mount.
These are a far more substantially designed bracket - and they come in widths of 16", and possibly more, if my memory hasn't faded to close to black:

I'm thinking if that target shelf isn't properly supported, I could then just use the board and put on some better brackets.
