What's the realistic budget for a quality 6-person outdoor dining set?

Across the candidates we synthesized, capable HDPE-and-aluminum 7-piece sets land between roughly $540 and $700. Acacia/teak 9-piece expandable sets push into the $1,200-$1,400 range. Below ~$500 for a 6-seat set, reviewers consistently flag durability and rust concerns within a year or two.
