I am putting the finishing touches on my 5.1 setup. One of the things i have been aiming for is a minimum of items on the floor but i am stuck for options on a wall mount system for my components (AV Receiver , DVR, BluRay and regular DVD)

Ideally, it would also have good cabling solution.
The only item I found that looks like what I am looking for has a 30lb per shelf limit and my AV Receiver is 32lb.
This is the basic look I am going for..
Circuit City TRIA 3 shelf system (http://www.circuitcity.com/ssm/OmniMount-TRIA-Three-Shelf-System-TRIAB/sem/rpsm/oid/185722/catOid/-18363/rpem/ccd/productDetail.do)

Can anyone suggest locations I can find such a thing?

The weight limit seems somewhat prohibitive, the shelf depth of only 15" is pretty tiny as well particularly when you add cables and such which will easily add an inch to whatever you're plugging into.

Is there any way you can mount your components in wall using a rack system? That's usually the best way to go, takes a bit more work for sure but you end up with a really professional, clean look. Not that expensive if you use pro-audio rack stuff instead of the middle atlantic stuff. I did mine for $250, and it's HUUUUGE 6 feet tall, 15 shelves, 2 fan units, and face plates for all the unused spaces. You could even do it with regular shelving for about $50...Like this

That does look great - unfortunately, it won't work in my case because I don't have the wall depth...
It looks like my medium term option (after saving) will be to replace my AVR with something smaller and lighter...

I know you said you wanted things off the floor, but you could always go with a 16-space rack and just load the top 10 spaces with stuff and leave blanks at the bottom. The only other thing I can think of would be a wall-mount rack, which would look horrendous.
