I use clear plastic containers from lunch meat for lots of small parts. If you eat the meat, the container is free. Large yogurt containers work well for derailleurs, hubs, and shifters, but the containers are not transparent.

Healthy Choice Steamers microwave dinners come with a fairly sturdy plastic bowl and a parts strainer, also plastic. Works great for washing ball bearings and small parts.

I found that the old Campy Gran Sport RD on my '64 Legnano will play nice with a 28t 6 speed freewheel if I back out the Campy dropout screws. Then I pull the wheel all the way back on the dropouts and the big gear clears the jockey wheel.

I found that double-sided velcro computer cable straps work well for securing my frame pump, without scratching the frame. They also come in colors.
