I think I paid around $300 for my tripod + ball head, but it’s also stout enough to hang an AR off, or a SLR with a very large lens.
Where better tripods start to become a big deal is when you start raising the neck, higher you more the more shake you get and the more it’s amplified.
They don’t make mine anymore, but it was something like this.
You can get a lot of flexibility depending on which model you get… I use mine when kicking back in a chair, prone, standing, you name it.
