I read Volume 2.
Saiyan might be even better than Piccolo Daimao. It doesn't have as much support from side characters, but I've noticed it's a bit underrated compared to most other Dragon Ball Arcs despite being good, and is a setup to Freeza, the best Arc. It might be bias on my end, but you know.
You know, in hindsight, I'm breezing through this series and really enjoying it. Maybe it's because I already know what happens, and it's much, much shorter than the anime. That, and I took a hiatus from Manga for months since I now dislike what the Industry has become, and Dragon Ball is a classic.
