I've got several of the Manfrotto air-cushioned (10xxBAC) stands (two 7', two 8', and one 12'), all are excellent. The 8' ones have a 2' diamater base, which is nice for small rooms. Any of them will hold a PCB Einstein 640 monolight, although I generally use the 8' or 12' if using a large modifier (a 48"/120cm octabox, for example) because the 3' diameter base provides better balance.
