Until I started using cw and digital modes, I pretty much identified with the saying, “life is too short for qrp”. When got into S.O.T.A.(see summits on the air page), I found that spotting can also make the difference to successful low power , compromised antenna ops.
Elecraft KX2 seems to the favorite many S.O.T.A. activators. A very tiny self contained station even available with internal auto tuner.(https://elecraft.com/products/kx2-ssb-cw-data-80-10-m-transceiver)
