@itsmelynda, I don't know if it's still available, but Roku is (was) offering a deal on a new Express device for affected Prime users:

You should be able to see any offers available to you there. Personally, I'd take the Ultra over the Express, but if you can get the $10 Express deal it's almost too good to pass up.
Any new device should be much better than your Roku 2 XD.
