Yeah, I agree that there seems like a lot of overlap with the El Cap. I’m planning to “upgrade” to the new one, as I really like the feature set of the new one, having more access to functions up top via the knobs, and a stereo input.
I’m actually putting my El Cap up on the auctions today. I bought my El Cap used within a year of its release and one that sold on the auctions here in Japan yesterday went for around the price I paid years ago, so I should get most of my money back from the El Cap and I can always pick one up again if I miss it for any reason.
