@ Tom E, here is my review of it. Its even got direct number comparison with the L4, beamshots vs L4, and side by side picture with the L4. Along with hopefully everything you could ask for. :)
Its also easy to mod, as seen in my review thread. :)
@keithd. Around 60$ is a bit pricey IMO. Around 50$ makes it decent value. Less than 40$. I ordered my second X6M. ;)
