The 2800/2900 is a great radio. Super beefy and the large screen and buttons are nice. I had one installed in my dash for years and never had a problem with heat even with all day use, mid power. I needed a few more features so my 2800 was moved into the garage and an 8800 put in the dash. The 8800, as described above, is much more delicate, has a much smaller screen and very small unlit buttons. I've got to be careful when pushing buttons because they are small and hard, unlike the rubberized ones on the 2800/2900. My finger or nail slips off and pushes an adjacent button all the time.
The 2800/2900 series is a great simple and easy to use radio. All my Yaesu's have had the same mic and all are fine. I don't bang them around too much and they are holding up fine.
