Best inexpensive remote control for multiple devices, including my Roamio?

Here's the deal. I've got a Coby TV, which the remote that came with the Roamio works just fine to power on and off.

I've got a Yamaha surround sound system which same remote will control volume. I've tried the trick of programming it's code as a power code, to get it to turn the system on and off, with no dice.

Now for the problem. I do not use the input selector on the TV, as I have multiple devices all using HDMI, and the Yamaha system has HDMI inputs and output.

So, I use the Yamaha receiver to switch input.

Now, ideally, I could just find a way to use the TiVo remote to do what I want, but I can't seem to find the info I would need to make that work.

So. I am looking at other remotes. However, I have grown quite used to the "TiVo button" on the top, and I'm fairly certain other non-TiVo remotes will be lacking that button.

I am a new TiVo owner, and so I come crawling to you guys for tips, tricks, and in this case, help deciding what, if any, remotes I should be looking in to.

I -really- don't want to spend a fortune on a remote, since I'm still not finished buying the other things a bit more 'important' such as TiVo Stream, and a pair of Minis to complete my network. But this remote issue is quite annoying, and if I can fix it fairly cheaply (or free, if I'm wrong, and I can do all this with the default remote).

So. Excuse my keyboard spew, but .. HALP? :)
