Brass is easier to work with, but Blender uses a jewelry welder to stick things together. You can solder brass, but it's crap to try and weld - the zinc boils off.

Steel brake line might work though. It's cheaper, available in a lot of sizes, just about every auto parts store will carry it, and it doesn't work harden as easily as some flavors of stainless will. It won't polish up as nice as stainless though.
