is this scanline generator good? has anyone used it? seems to no psu need as well? vga in and vga out, so it's seems usable for wii, ps2, dreamcast, x360 and ps3 ( great for the those classic ps1 2d games), thx

I already have xrgb 2 plus, but it's in storage as I have kids and had to compromise on too many game related boxes, but this seems small discreet and no need for psu, seem perfect
