It's hard to find smaller quantities at decent prices. I've used Waytek for years.
Delcity is another good wire and part vendor.
http://www.delcity.net/ The electrical depot is a good place to find small quantities of Delphi Packard, Weatherpak, GT150, and Metripak terminals shells etc. Deutsch connectors with machined terminals. Mini & Micro ISO Relays sockets and terminals.... Quality mid range tooling that won't break the bank too.
