Handlebar Bags

I couldn't find a specific thread for these, so thought I'd start one.

As per correct cycle geek behaviour, I've spent hours on that t'internet reading reviews, noting down dimensions, pros, cons, spennyness etc, and have not arrived at any conclusion.

I am planning to do some modest tours / day a->b rides using mobile phone to navigate and want somewhere to store battery pack for phone, food and a few other bits and bobs which are handy to access on the move. Ideally I'd want to be able to have enough room on the bars to also mount my phone with a quad lock. Garmin Edge 500 will be on the stem to keep it out of the way.

Any thoughts? Will probably be paired up with a Carradice Nelson on the saddle, if I can find my old one or may even buy another one. Just for enough space for a change of clothes for when I get to whereever I'm going.
