If you are interested in purchasing color to experiment/work with in the hotshop, below are a few reliable vendors:

Olympic Color Rod

C&R Loo

East Bay Batch and Color

There is only one pipe/punty maker I strongly recommend if you are going to invest in your own: Spiral Arts. You will not regret. The  large cup pipe I find to be very versatile for most things. If you tend to blow larger, perhaps step up to the standard workhorse.

Most of the tools in the shop are from Jim Moore, if you wanted to get your own tools (like diamond shears that actually cut.)

Spiral Arts is also the main US distributor of Carlo Dona tools. Personally I find their jacks to be “scratchy,” but everything else dreamy.

Some people are very fond of Cutting Edge Diamond Shears for their lightness/size ratio.

Jasen Johnson started making some very sweet tagliols and sculpting tools.
