Does anyone here have any experience using the Lastolite Strobo Gobo? From some quick searching it appears to be the only Gobo holder for speedlites that I can find, and I really like the idea of all the possibilities something like that could open up. Seems awfully expensive for what it is, though. If it is indeed the only such item on the market, I would definitely want to know how hard the shadow cast by the speedlite/gobo combination is before I fork out for it. Especially since from a test I did at home it seems like there would need to be more space between the flash head and the gobo than the strobo gobo provides in order to get the kind of shadow edge definition I'm looking for. It also strikes me as the sort of thing that wouldn't be *that* hard to rig up, DIY fasion. Anyone ever tried that and/or have any tips on how to do it?
