Yep, Curious Goods is where I get all my supplies too (pipes, screens, etc.). Good place, nice people.

I had trouble finding it my first time around. Here's the address and a link to maps.google.com; or give them a call at (919) 834-8628 for directions.

They're right next to a little mini-mart type place, a little over a mile from I-440, on your left if you are going east on Hillsborough Street.
