I realize you are looking for a 100w amp but if you like building kits, the 50w Hardrock is a very fun project and works well.
https://www.hobbypcb.com/index.php/products/hf-radio/hardrock-50-hf-power-amp I built one and have used it on SOTA activations when I want something more that 10-15w. I also have two KXPA100 that I use often and also enjoy.
