I was planning to build a rack, since I needed one that held 3 tub sizes... but after trying to plan it out, and talking with the person who was going to build it for me, it just seemed too complicated. Luckily I was able to find one pre-made that suited my needs, and it should be arriving this week. But hey, if you have the time and abilities, I'd say go ahead and make your own - then it will be exactly as you want.
