I'm wondering what would be a good wireless microphone for my Canon GL2? One that will work well but not break the bank.

Jason,

You've got some searching to do my friend! Lots of info/discussion on the topic on this board. A good start would be GL2 and wireless. I'm betting you'll get more info than you'll imagine!

Jason,
there are huge threads on this subject, search around a bit.
What is your budget? Banks vary from person to person. Is 100.00 too much, or is 1K too much? 500.00 more in the price range?
Components or prebuilt package? Lotsa questions, but the forum has lotsa answers.
