The whole kit, I would recommend. Especially if it's your first build. We bought the Anovos and there is definitely a wait. But, they delivered when they said they would, right down to the wire.
As far as the build went. We didn't rush and it was fun. Rare earth magnets are a serious plus during the build. I bought 1/8" diameter magnets. Too Small. A friend loaned us his 1/2" diameter. They worked great.
One other suggestion, again if it's your first build, strongly recommend E6000 glue. No lie when they say a Trooper's best friend.
Good luck.
PS, Don't be afraid to ask for help.
