I let the cat out of the bag the other day when I mentioned this on another thread so I might as well make this official now. Tomorrow I will be going to Animal Plastics and personally ordering a new 4 shelf 41qt rack that looks just like the one I have now, shown below. I will have to pay half down and then the rest when its finished 5 weeks later but all things considered, its worth the wait. Its still quicker to do it this way than trolling CL until one comes up.
Yes, Animal Plastics is located right here in the Des Moines metro so I find that to be quite convenient as opposed to ordering online and paying for shipping costs. I am so looking forward to this.
