I already have inpa, winkfp and tool 32 working with simple coding cable. I want something rigid to update different modules. On reading forums, it suggests that 2RAD, CIC and some other modules require icom cable.
I have not used icom yet. So my understandig from your post is that it is cable like inpa / NCS expert coding, but better in terms of working and functionality.

If that is true, where can I get one which should do the job, but should be worth enough spending to justify its price.

Thanks.
