My complaint with the mesh baskets is that if/when you want to divide your plant, they are next to impossible to disentangle the roots from. The edges of the holes are sharp and cut/break the roots so unless you painstakingly cut the basket apart and remove the pieces you're really damaging the plant.
Looking again at both Scott's and Daisy's plants, I think I'd be inclined to fasten a raft of cork to the bottom of each plant. Catts happily fasten their roots into the crannies in the cork, and I have at least 5 plants growing happily on bare cork rafts. When the plant outgrows the raft, I just fasten a bigger piece of cork onto the bottom and "grow" the mount. If I wanted to divide the plant, the cork either breaks easily or you can cut it with a serrated bread knife. In 3 years of using cork, I have yet to see any of it breaking down at all. It's light, strong and beautiful.
