Looking for a Brick and Mortar electronic components store. I'll be in Sunbury on Thames for a few weeks starting today. I'm in the middle of a arduino project and need a few components. (soldering iron, screw terminals, wire connectors, project box, etc...) Any suggestions for a place where I could pick this up available via public transport within an hour or so? I'm from the US, and not familiar with any of the store names to look for, or which may be worthwhile.
