Here they are in no particular order:
| Team Delta | A great site all around, Dan has great bots and makes great electronics for robotics. An excellent place for a new builder to get started. |
| Tower Hobbies | Almost everything R/C. A good place for radios and accessories as well as batteries, motors and chargers. |
| Servo City | If you need servos, this is the place to get them. They will even hack them for you if you need it. Best of all good prices and free shipping. |
| Hobby Lobby | A lot of stuff that Tower doesn't have, particularly in the motor department. They have an awesome selection of airplane motors and batteries, a good place to find that killer weapon motor for your antweight. |
| Robotcombat.com | Jim Smentowski's site chock full of all sorts of robot goodness. A daily updated links page plus all sorts of useful tips as well as a cool database of robot teams from around the world. Another great place for the new builder to get started. |
| McMaster | Hardware, raw materials, and some tools. Chances are, if you need it to build the mechanical parts of the bot, they have it. I particularly like the plastics and fasteners section and they also have a lot of wheels, chains and sprockets and all sorts of other goodies. |
| Online Metals | A good place for the hobbyist to go to for metals. They will sell in small quantities (down to the inch in most cases) and have a good selection of steel and aluminum as well as brass, copper and even some titanium. |
| Team Mad Cow | Jr. is a real cool guy and builds some great bots. |
| NERC | The North East Robotics Club where I fight all my bots. Here you will find club info and the rules for the competitions I enter. |
| NERC Delphi Forum | The Delphi forum for the North East Robotics Club. You can find help and answers to your bot questions here as well as progress reports and upcoming event info. |
| All Electronics | A really cool electronics surplus store. As it is surplus the stock changes all the time, but you can find some neat goodies here if you keep your eyes out. |
| Enco | My favorite place to find tools, reasonable prices and almost every kind of machine tool you might need to build your bots. They have many metalworking tools that you just won't find at your local Home Depot. |
| Harbor Freight | Discount tools, and the source of the ever popular and cheap corless drill motors and gearboxes, usually on sale every other month $10 for the 9.6v, $15 for the 12v. Also some good metalworking tools. |
