Welcome.
If you like versatility but lack a PC probably the Diamond controller is a good build to start it can cha n ge colors and sound fonts without connecting.
Personally I don't like changing colors on most sabers. I feel a sabers color is part of its personality. So prefer the single colors with an Obsidian V4. That can still change sound fonts on the go for a bit of versatility.
I so agree with the color part!
I went Emerald on my first sabers, but the next was just premium sound. Choosing the color is an important part of the purchase for me =).
