I bought a nice tumbler from garden supply about 10 years ago and it has held up well. I think I paid close to $200 for it. It has more than paid for itself. I also us a old trash can that had seen better days and a free huge black nursery pot, almost anything will work, it just depends on where u put it and what you want to look at or what you can hide.

I have several very simple large bins made from cylinders of galvanized 1/2" hardware cloth. They've lasted me many years now & are easy to move around. If you're not too concerned about appearance, it's a great inexpensive choice - esp. since it's quite handy to have a couple side by side to shift contents as you harvest the compost. Mine are simply fastened w/ some gardening wire &/or metal shower curtain clips.

& if appearance is a concern - that is, hiding the bin from the casual eye, sometimes wild passionvines grow up over the outside of the bins, attracting butterflies & making them look like a green hedge.

FWIW, you might also find some interesting ideas over on the Soil, Compost & Mulch forum.....
