Floating shelves

Hello chaps,

I am moving house, and intend to fit my system on shelves on the wall, as my 1 year old boy will destroy anything he can touch!

I have 5 or 6 units and would like them stacked one above the other.

I have seen the Vogels, Alphason Aragons (wall mounted), and Stands Unique's Transition wall supports (expensive)

I love the transitions, but they will work out at over a grand, which is a bit too much money...would prefer to keep it to under £400-500.

Any other suggestions, or recommendations, or thoughts on the above?

Thanks guys
Siy
