I had an 8800 in my 40 and decided to sell it and use a 2900 instead. I never used the 70cm and although I miss being able to listen to both the simplex and repeater at the same time, I don't miss how tiny and delicate the 8800 seemed to be compared to the 2900. The 2900 is much better suited to being in an open 40. I put a 2800 in my Hilux as well. They are both easy to use, easy to see, and have tough construction. I also like the higher power of the 2900 and 2800 for peace of mind when I'm far away from repeaters and cell coverage.
