Amazon has this for $100. It’s what I bought for my starter and still use almost all of the equipment.

Depends on where you are in the world. Amazon can get you what you need, but not always at the best price.

I would really suggest starting with a 1 gallon kit though. It makes for less expensive mistakes and more control while learning. You really want to do your primary in a bucket though.
