All grain brew stand designs???

I'm looking to improve my all grain setup and thought a brew stand would be good, any thoughts on a design? I currently brew a three tier gravity fed system thats a bit ramshackle and could use something thats a bit stronger and sturdy.

Andrew,
 First, it depends on what size you are brewing and how much room you have for the system.  I've seen designs that range from the simple to the elaborate.

 I don't have one personally, but you might want to take a peek at the Brewtree design.   It looks relatively compact and simple for a 3 tier system.  If space is less of a problem you could try a stair step design.

Cheers!
