well.. in order to fully understand the differences between the two systems, you (the blackwidow system) have to provide a much more detailed list of specifications..

i know very little about wireless technology.. but can probably guess.. that the hitech system has a much longer range.. just from looking at it's antena...

once you publish the specs.. i think all of us will be able to distigesh the differences better.. and to point out, if there ARE any MAJOR differences...
