This is apples to oranges. The original discussion was about strut bars. If all you're looking for is "good enough", I think you'd be hard pressed to discern the performance difference between the $100+ Neuspeed bar and an eBay bar costing less than half that (and after all, $80 is $80 as you pointed out). Does the fact that the Neuspeed bar costs more make it of higher quality or effectiveness, even though the basic principle of its design is more or less the same (i.e., linking only the two towers)? My original argument is that the triangulated bars are a more effective design, plain and simple. If you aren't limited by a racing class and you want to add rigidity to the car by adding a strut bar, the triangulate bar will perform better. Is it more expensive? Sure. Are there people that want that next level of performance, even if it means spending more? Of course (look at the many people running custom headers and Hondata systems rather than off-the-shelf pieces and a V-AFC). We're all familiar with the concept of diminishing returns, it's just a matter of how much you value performance over cost.
