Where+Can+I+Find...?

Getting good supplies that are affordable and of good quality can be time consuming, expensive and frustrating!
But some people have been doing this for a while, and so may have very dependable vendors. Maybe someone has a place where they get some very cool materials. Maybe there are resources for free supplies that others could use also.

This might also be the place to compare materials. Being able to ask how a particular product works before you spend the money on it could be very helpful. If you have a question about a product, someone else may have the experience to be able to advise you about it.
