I am more interested in benq 6100 or 6200
6100 has a 3000hr lamp, 2000:1 contrast, 1500lemens, and 3x color wheel.. It's brigher than X1, better contrast than x1 (when comparing against RGB mode not RGBW mode), faster color wheel, the only thing it lacks is the DCDi(but this is a very very good feature for SD material)
