Okay, while he seems fine as-is, I'm just a bit wary of the ability for Saiyans to grow more powerful every time they end up near death.

I'm not very familiar with actual canon DBZ, but I know that's something they can do, and that power levels get to "blow up planets easily" level. I'd like to avoid stuff like that.

You don't have anything to worry about right now.

Raditz is the very first villain in DBZ. Because of escalation, he's practically a mere ant compared to androids, pink gummy demons, and even gods. It's to the point where Team Four Star made the Power Level system's measurement for one unit be called "Raditz". 

Though this [i]is[/i] Dragon Ball Z. Frieza could toe-dance with Goku at his highest level just after training for four months, so...

Eh, screw it, I'll leave Raditz power level to the discretion of his player [url=http://www.youtube.com/watch?v=BsMSiVn6vpQ]because...[/url]
