DelGatoGrande,
I'm not sure what your problem is with the Cortex (or it's dealers) but it almost seems like you have an alternative agenda. Both the Cortex and the iGyro3e are good systems and both have their pros and cons. I have had customers by several more Cortex gyros after trying one and also have a customer who has swapped out an IGyro for a Cortex and prefers the latter. Individual preference is a big factor in whether one system is better than another but I would suggest that the difference isn't as clear cut as you are trying to suggest.
As an aside, you can also adjust individual gains of the Cortex via a PC and the cable is included in the box (not an optional extra).
