I bought the icom ic-440, and I think it's great, but exxy.
I mounted the unit to the next of the cluth pedel to get it out of sight without having problems getting to it.
I used the mic extention cable to run through the centre console, poking it out next the drivers seat.
The mic mount is stuck to the dash, using those 3M adhesive strips, under the hazard lights switch which has had plenty of use and works great.
I found the icom mic bracket was alot stronger than what I have seen from GME and won't bounce around.
I couldn't fault anything about the unit. It has heaps of features, yet stays simple to use when doing the basics.
