You may be right. I am on the Roku accessories page and it doesn't look like my remote is even sold any more. Mine is the voice remote with headphones but it does not have the two shortcut buttons.
I got the Roku Ultra LT back in November and I vaguely recall only spending $40 for it new. It looks like just the remote it came with is $40 now! Might be worth picking one up on eBay or something?
