I have been going to this place for years. It is a small, family-owned electronics surplus store. They have all kinds of electronic components, wire, project items, etc. This is the first place I go when I need an electronic part for work or home. It is a really good place to look if it is for an older or legacy product. Even if they do not have the part, they can most likely tell you where you might find it.
Another big plus is that the employees are very helpful and quite knowledgeable with any questions you might have. This is something I have noticed is extremely uncommon in retail chain stores like Fry's or Radio Shack.
