I was about to purchase my first rack system as well, but I was getting frustrated with how expensive they all are. I decided to put together my own using plastic storage racks and couldn't be happier. I can post pics if you want. I suck at fabricating anything but this was really easy, not very time consuming, and best of all I have a solid rack that holds eight 28 quart tubs that altogether was under $200, including the tubs and flexwatt. I got the idea from a youtube video I came across. It turned out so good I'm about to make up another one that will hold at least twelve 12-15 quart tubs, and another that will hold like sixteen to twenty 6 quart tubs. I'm telling you if you want to save a couple hundred bucks this is the way to go. Let me know if you want me to post pics.
