I have the SB-80DX which my wife got originally for her F100, and also an SB-24, and a whole collection of connectors. The DB-80DX is very versatile, and includes a remote trigger, but it has few buttons for its functions, and takes getting used to. You can't adjust the ISO once it's turned on, so have to turn it off and on again for that. The SB-24 has fewer features and fewer low power functions, but works well and you don't need instructions to remember what button to push. I like, also, that I got mine for $2 at a junk sale, which seemed a bargain too good to pass up.
Among my random assortment of cords are a couple of ten foot multi-flash cables, which make for interesting effects at times, allowing (with intervening bits) up to 20 feet between flash and camera, and allowing one to illuminate a single distant object or place.
