[Walmart] Tp-link Archer C7 - $58 Linksys EA8500 - $118 YMMV
Edit: Also spotted the DIR-868L, and WRT3200ACM for $158.
Also, I happened to find an EA8500 for $118 on clearance as well.
Both are YMMV and the EA8500 isn't listed on the Walmart website anymore other than from 3rd party sellers. Both also support DDWRT.
