Tentacle Combat Robotics

	Team Delta: your source for high-quality robot parts, books, and information.
	Microbotparts.com: miniature radio receivers and other unique parts designed for maximum function with minimum size and weight.
	Sherline Miniature Machine Tools: Mr. Tentacle's Choice for bot building.
	McMaster-Carr Industrial Supply: if McMaster doesn't have it, you probably don't need it. Everything for the robot builder (or any kind of builder, for that matter.)
	Grainger: Grainger is strictly wholesale, which means you need to be a business to buy from them. A state tax ID or business license or a check with the business' name on it are enough to convince Grainger to open an account for you. Grainger stocks some items that McMaster does not, and has local over-the-counter sales locations in most cities of any size.
	Stock Drive Products: a cornucopia of drive train parts, primarily timing belts and pulleys, small gears, and couplings of various kinds. On-line ordering is very limited, order their catalogs and order by phone. SDP-SI has manufacturers reps in many cities, so ordering can be a local call to a local business.
Surplus Center 1-800-488-3407	Surplus Center: a terrific source for DC motors, hydraulic components and more.
Electronic Goldmine	Mr. Tentacle's favorite electronics surplus dealer. Common components (resistors, ICs, LEDs etc) in volume and at excellent prices.
All Electronics	All Electronics is another electronics surplus dealer well worth checking out.
Jameco Electronics	Jameco is a "full service" electronics distributor. Good prices and great service. Discounts available for Robotics Society of America members.
Newark Electronics	Full-service Electronics distributor. Newark is one of the largest electronics distributors in the country. Their catalog is truly vast, and pretty much required if you are doing to do much ordering.
Digi-Key	Fuill-service electronics distributor. Like Newark, you need the catalog to order, the web site is not set up for browsing.
