If I buy the whole 6 meter length of copper I will only need 2 meters would people be keen to buy the left overs copper tubing?
I doubt you would have an issue getting rid of 4" copper here. Ditch the coiled condenser build a shotgun if a challenge doesn't worry you, or a liebig for simplicity.
If you build a 2" shotgun and make it modular you can use it down the track on a bubbler.
If you can build a pot still and afford a 6m length of 4" personally I would build a bubbler. I have just built one and is very do able for a newbie. Albiet a bit of work. Or keep enough 4" for a bubbler down the track.
It is a very rewarding hobby and if you like a drink you will love the hobby. Its fairly easy to make a good drop once you get the hang of doing cuts..
