vegetable garden design software review?

I am looking to purchase some software for designing vegetable gardens. We really have our garden plotted out, but our group is wanting to put the layout of our garden on our website, and we were hoping to find some software that would allow us to do this. I found some software called "3D Garden Composer", but was hoping to find someone who has already used it and their opinion of it before I bought it. I am also open to suggestions of any other good software that anyone has used as well.
