I use a loomis venture. $100 flat. It's been beating kings for a number of years now.
I am not wild about taking it to salt, but meh... it'll do.
It's not a large arbor, but it's a line holder that has a good drag.
If you are getting a reel for kings, make sure the drag can lock down tight without failing or putting a flat spot in the drag bearing. You will need both hands on the rod, and if line is slipping, you'll never land a king. The venture can handle that, and is damn near smooth enough to handle the crazy runs. It's a little rough there compared to something like an abel, but again, it'll do. After three years, it started to kick into freespool now and then if I bump it on something. Doesn't happen when there is tension on the spool, so I don't worry about it.
