I'm in San Francisco and I go to Franciscan Hobbies, like 20min away. They are awesome. Very nice staff, and they know alot. They exchanged my battery even though I told them I was the one that melted the wires, and I didn't even ask for an exchange, I asked if it was safe to use. And I wanted to buy some stuff which they had in stock, but they told me to get it at a hardware store if I wanted to because it's alot cheaper. What nice people.
