I am a huge fan of this store, in fact I'm not sure it's a store... it's more of a community! If you need DJ equipment, they can definitely help you out and their rates are lower than what you'll get at Guitar Center. Plus, they will work with you to make sure you get what you need (and want). They also sell DJ lights, not my current needs - but good to know they have it.
The community aspect is that they offer free sessions to introduce extraordinary world of DJing to newcomers. If you're looking for digital DJ tips, go on any Tuesday from 4-6pm. Or, if you're into learning more about the classics... vinyl (old school DJing), visit MC Audio on Wednesdays between 3:30 and 7:30pm.
They are great at igniting (or re-lighting) the fire and motivating people to keep at it. I plan on visiting them regularly!
