Bert Stephani's Light Stand Box Strip Light
For the record, I have nothing against store-bought strip lights. It's just that if I have a limited supply of money, I'd rather use it to buy the things I cannot make. And I can make a strip light modifier easier than I can make a D3.
If you in the market for a light stand, don't toss the box that it comes in. And if you are in the market for two light stands, you may be able to get all Martin Schoeller on someone on the cheap.
