I have built many racks (and sold every one). I have also bought.

I have just ordered a 6 high 32 qt Animal Plastic Econo Plastics. This time around, I didn't feel like the time and effort were worth it to build.

Don't get me wrong, the best part of a home made rack to me is building it. But since I live in an apartment now, I had nowhere to work.

A good way to do a test run is to just build a small 2 high rack. That will give you experience in spacing and such. I have learned more from mistakes I made than the things I did well. And each build was better than the previous.

But don't feel like a failure if you simply order one. It sure saves a lot of hassle.
