Bi-Pod Recommendations

I've recently started getting into long-distance shooting at ranges between 200 and 600 yards, and I'm looking for a new bipod recommendation for my Daniel Defense Delta 5. I currently use a Magpul bipod, but it has a lot of play in it and never seems to feel secure. What bipods are you all using for shooting, especially for prone and bench setups? I looked at Atlas and Accu-Tac website and was overwhelmed by all the options.

Thanks!!

Edit:

My budget is between $300 and $400.
