Best plugin for Prev/Next buttons?

I would like to add simple Prev/Next buttons (not huge text boxes) on my posts, and perhaps pages, so the viewer can just click to the next post without using the menu.

I tried a couple, but they are not what I want – a simple Prev button and Next button near the bottom of the post/page that I do not have to code to a specific link, as I wil be moving posts around..

Thanks for any ideas
