Actually, the JVC GY-HD100

Actually, the JVC GY-HD100 is only 720, not 1080.

And I think I am going to go with the XH-A1 myself because of the XLR inputs and a few other features that the FX-1 doesn’t have.

You just need to figure out which one has the features for what you want to do. No need to spend an extra $700 if you don’t need the extra features.
