The Voyager kit comes with pretty much everything you could possibly need. Anything else scrap building will suffice.
FYI, the Voyager kits total up to about $110 USD at most, the Aber kits are about $300 USD, almost three times the price!! TFTM said he paid under $60 for all the kits, that's a hell of a savings over the Aber price. I too bought mine early into release for a cheap price as well, about $60.
This is the quality of the Voyager kit in the hands of an amature, as I'm sure you've seen.

Check out what TFTM shared with us a while back. This inspired me to go the Voyager route.

On top of that people actually say the Voyager clamps are better than the Aber ones.
