See, right after I told you to not make this complicated .

You will be fine with the digital version. The reason that people lean towards the analog is because the needle doesn't react as fast (read - "less jumpy") as the digital version. Many people extole the virtues of the digital rather than the analog - not a life threatening issue.

Try the digital. If you get motion sick watching the needle, take it back & get the analog. As I said earlier, either will be fine.
