Guys, there are several BIG differences between the EX-1 and EX-3. The viewfinder on the -3 is a HUGE advantage over the -1. I have shot with both and own an EX-3. It also is MUCH easier to hold steady handheld because it is shoulder mounted. The lens and multicam cabability are great too.
Also, there is no problem with using XDCAM Transfer to download your clips. It is fast and you can drag them straight to FCP with no render. FCP makes a compatable timeline automaticly. This is about as easy as it gets.
