LumiQuest Bounce: Worth It and Which One?

Hi all,


I have a 580EX II and I use it on my 40D / XTi. I have used the Sto-Fen Omni Bounce on it in confined spaces (i.e., when I can bounce off the ceiling) and I have been pleased with the results. Do you think it's worth getting one of the LumiQuest Bounces (and, if yes, which one!!!) to use in places where there is no low ceiling?
