Cons....removes fingers from keyboard, usually the left hand. Takes up space on a desk. Uses USB resources. (all these are minor, IMO) They cost money.
Pros...Allows for quick movement on the timeline, somewhat more accurate than using JKL keys. Most shuttle devices have assignable keys. In my case, I've got it set up for enabling/disabling ripple, splits, delete, and all my multicam tools for Ultimate S 2.0. I've also got one set up to launch Ultimate S 2.0, launch my Normalize script, and Audit script.
Someone loaned a shuttle to me for a few days. I tried hard to like it. Didn't miss it for an instant once it was gone. But, I always try to use the keyboard instead of the mouse, whenever shortcuts are available. JKL is very precise and very efficient.
To me a Jog/Shuttle device is one of the most important tools for editing. It can be a great workflow-booster because quick navigation and main editing features are close beneath and I find it bit more economical than using a regular keyboard.
I have several presets for my Jog/Shuttle which I use for different stages of work.
But in the end it's all up to you to determine wether it's good or useless for your editing surroundings. Best is to test it before buying one.
It's really depending much on your personal preferences.
I got myself a Shuttle Xpress some months ago and I absolutely love it.
Basically I leave my left hand on the shuttle and my right hand on the mouse for 95% of my basic editing work (rearranging clips etc).
I have programmed my favorite commands to the five keys (rewind, delete clip, toggle ripple edit, split, playback) and hardly need more than that.
Of course, when it comes to adding effects later in the editing process I hardly need the shuttle any more. But JKL keys are still working - so no problem to go back to the keyboard for that stuff.
So give it a try.

What about the left hand co-ordintation bit - I am right handed so would there be a problem with co-ordianting the left hand in with the right hand use of mouse?
You will get used to it. I'm right handed also. No problem using the Jog/Shuttle left and using the mouse on the right. All you do there with the left hand is moving a wheel and pushing a few keys.
I don't think there's that much choice, apart from the Contour AVS units there's the shutle controls in the Mackie control Surface and that's about it as far as I know.

The Bella Keyboards also offer a good jog-shuttle on board, the Griffen knob can be programmed as a jog/shuttle, same for the Tascam, Behringer, JL Cooper, and other mixer/interface devices. Some are very easy to set up, others are not.
I use both the Bella and the Contour on my main desktop system. I find the Bella easier for speed with straight ahead editing, because then my left hand never leaves the keyboard.
