Go to Microglobe and get a Lightsphere from them, it's a knock-off and much cheaper and bloomin' brilliant (in my opinion!)
Another vote for it. Its fantastic for shots inside but don't use it for outside shots. Also have the collapsible version and its much better.
I had one and sold it on eBayThe problem for me is that they waste a lot of light - as much goes behind the camera as it does above and in front! If you're shooting in a room with a high ceiling, you'll lose even more light.
I bought a Stofen diffuser and have invested in a second flash, which I can use to provide some fill-in and bounce off ceilings etc.
The Gary Fong is ridiculously expensive too :nono: There's a reason why the guy is a millionaire.... £50 for a bit of moulded rubber? :nono:

£40 for the lumiquest is still quite a lot when you can do a similar setup for about £3 using the instructions here. I get the foam for them from Hobbycraft at about 80p per sheet. Works a treat, lasts well and gives nice soft illumination. Takes less than 5 mins to make too!
