Haha - I just looked at those Harbor Freight ones someone linked. That's the kind I was picturing, whether plastic or metal. Some are kind of spendy, but if you look at the coupons, there's a 3-shelf steel one for $40 on sale (regular $50). There's a 2-shelf steel one for $38 regular, so you could use your 20% off coupon to get it around $30. The 3-shelf will be much sturdier, however. The best thing to do with HF stuff is look at it in person to be sure it's of sufficient quality and function. In this price range, there's not much point to making your own.
