Which weapon should I get?

I'm still quite stumped on which Ec item I should get, the Flamethrower or a Red Light Saber. To be honest I don't NEED either weapon, I have a katana which is nearly as good as the saber and the Flamethrower might become like my other guns. Rusting in my inventory because I'd rather use my souizen which is better in my opinion. Please, help me out as fast as you can because I just need 2 ecs and a piece to reach 100.

Flamethrower.
You're going to have so much fun spraying it at mobs. Trust me. I'm a victim.

I would say flamethrower. It may seem worthless, but I've seen Romeo Wolfy use it and it's awesome.
