Chevypower, you mentioned the Sony EX3. Do you mean the Sony PMWEX3, the camcorder that lists at the Sony site for $9,990?
If so, that's not in my budget (in fact, it may not be on my continent!) I was thinking more like ~$1,000 or maybe a little more for a camcorder.
I guess that this is something that designers of consumer camcorders, below, say, ~$1,500, don't take into account. (This would make sense given that most consumers buy a single camcorder for their needs.)
I once saw a musician with a t-shirt that read "Fix it in the mix" and I suppose that's where I'll be working to align tracks from different camcorders.
It's all an adventure. Thanks again for sharing your knowledge.
