where to get tools

[sam]

various events have made me decide to tighten up the wiring situation in my cab.  

where do people turn for equipment.  soldering stuff, odd cables, and connectors?

radio shack is ok, but not great.  their catalog is a little better as it sells professional grade items, that aren't available in the stores.

in particular i'm looking to get a good quality soldering iron and related equipment.

any ideas? either online, or in the manhattan area?
