I never had a problem with east coast. I never bought anything big from them, but they always had what i needed. The shop may not look that organized but for the most part, dave knows what he has. His helpers arent the best but whatever. I will say one thing, 90% of his customers are either worthless scum bags or people with zero clues.
They are the first place i run to if i need something in a pinch. He has a huge inventory that most people dont even see. Dave is actually a cool dude once he gets to know you and realizes your not his typical scum bag customer trying to pocket parts and walk out the door. With that said, i only turn to them for parts when needed, they would not be building anything for me, however, he has some pretty cool off the wall projects in the back, witch im sure most will not work, but there cool.
