I'd estimate it's in the 300 to 400 rpm range.
Hi YesMAN,

If you're concerned, you can always have your dealer check it out the next time you have an oil change or other scheduled maintenance visit. They'll be able to diagnose it or give you some peace of mind. Worth the trip, I'd say.

Bear in mind it's not violent shaking or something.

If it was an actual mechanical issue (misfire, etc) that was strong enough to shake the engine, the ECU would've picked it up and given you a check engine light. I woudn't worry about it if I were you.
Thanks for sharing your experiences, dutd33 and cbdallas. Great info, and I'm sure YesMAN appreciates it.

Feel free to shoot me a PM if you have any other questions,
