I've had to replace leaky caps in several of them, and repair apparent lightning damage to another, but otherwise, they seemed to hold up pretty well.
The 55 watt VHF unit I had did get pretty warm, pretty fast, though.... I would suggest running them at less than full output, and adding fans and/or more heat sink material. They're cheap enough to be throw-aways, these days.
