The budget tool tube is from Harbor Fright:

You could also buy one of their tool rolls, or make your own:

I don't have a bike now but my car's tool bag is full of Harbor Freight tools. Cheap enough to be stolen, and if I have a problem where the tools are breaking I need to call a tow truck anyway.
