channelume return versus traditional notched and bended Aluminum return

Hi,
We have been doing the traditional channel letters by notching and bending aluminum coils for quite sometime now. I came across the chanelume letredgereturn product recently http://www.channelume.com/. They claim one can produce quality channel letters easier than traditional method. Does anyone have experience using making channel letters using channelume/letredge? I need to compare channlume vs traditional channel letter in these areas

1) cost
2) reliability
3) Actual fabrication time
4) any other considerations.

Thanks!
