Yup. I avoid cheap optics like the plague. Sooooo not worth it. I've been tempted to buy a cheaper red dot now and then for a beater AR, but I've yet to go there.
While I certainly appreciate the quality of optics like S&B, USO, etc, I tend to gravitate to value optics like Nikon and the Vortex mid to mid-high lines, like the Viper PST. One day, I plan on a bolt gun with something like a Nightforce or something in that range, but for now I can only dream.
