I use a Mackie Control MCU (one of the older units) and I love it.
It has 8 motorized faders and can do fader, send, pan automation among other things.
These units are pretty cheap used 300 USA dollars at GC. I see them all the time because im searching for the EXT (8 more faders).
However if you are looking for something smaller the Faderport is a good choice. I haven't used one but I have heard others say they work well. those have 1 motorized fader and some buttons.
I thought about the Faderpoint years ago but I need more options than that. the Mackie MCU has buttons for cut/copy/paste, it opens PRV (different views) has a jog wheel / scrub, zoom buttons plus a slew of other features.
Most importantly though, to me anyways.. is it just works. it connects through midi so no need for a driver is necessary.
plus cakewalks Mackie protocol is set up for it and very customizable. you can also do things on the Mackie you can not using a mouse, like fine tune pro channel ratio rates on compressor modules and things like that.
With all this said, I still use my mouse and keyboard shortcuts quite often to be honest. so I like using both.
