What COTS parts would you like to see?

Try this: http://www.andymark.com/product-p/am-2899.htm.

It's more expensive than your standard pot, but much less nosiy, much smaller, and comes with a pre-terminated cable.

AM Stealth Wheels?

4. Something to help with chain tensioning, perhaps a small kit? (I have no idea how this would work though).

If this is a chain that never spins a full revolution (arms, elevators), MISUMI sells some made-for-chain turnbuckles that connect with masterlinks.

5. A motor testing kit to check for damaged motors.

On the topic of rollers, I've found the secret is the 1.25 x 0.0625 tube. The ~1.125 ID makes a number of COTS hubs and bearings fit nicely.
