I've used the larger tool bags (like from Sears or Home Depot) for a monolight. Found an appropriately sized cardboard box to fit inside the bag, then lined the box with a sheet of bubble wrap. Not an arrangement I'd want to use for everyday use, but worked well for occasional use. But the bag only fits one monolight (it was an older White Lightning Ultra) with reflector and cords. The one I like best is: http://www.amazon.com/Bucket-Boss-Br.../dp/B00002243C But I think it can be found for less.
