Wanted: Messenger bag for commuting, size M, any color

Hi all,

I'm looking for a messenger bag for commuting around London. Won't be carrying anything unusually heavy in it.

• Any brand, as long as it's durable and has good padding. Stabilizing cross straps a plus.
  
• Size M.
  
• Not hugely picky about colors, as long they don't make me cringe.
  
• Don't care too much about condition (lightly used, heavily used, etc) as long as it's serviceable and won't fall apart on me any time soon.
  
• Looking to spend £50 max. Less is better.
  
  

If anybody has anything that fits the description, please let me know. Cheers.
