Penn 209LC, or, just line counters in general

I'm considering an upgrade in the rod and reel department. Does anyone use the Penn 209LC, or for that matter, any conventional reel with a line counter? I'm pretty new to rockfishing, and it seems like a line counter could be pretty useful. Or is it? I can see how trolling with a line counter, but without a downrigger, would be pointless. But it seems like a line counter paired with a fish finder could be advantageous. Thoughts? Experiences? Do the extra parts of a line counter help, or just get in the way or add to maintenance?

or the most part you will fish RF on the bottom so the LC isn't necessary. I do use a LC for Salmon. Its a Daiwa....FWIW.
