Doubt about MR soundboard

[Ezequiel]

Hi people! Im from Argentina and I intend to construct my first Lightsaber. I wanna buy a MR soundboard but there are 2 versions:

1: Darth Vader 3 AAA bateries

2: Darth Vader 6 AA bateries

But I dont Know anything else.

I Wanna Know which is the difference and which is better (Soun, bright, etc)? And any other information that you can give me.

Thanks and sorry for my very bad english!

The only difference is one uses 6 batteries, the other uses three. Both are wired for 4.5v (the 6AA version would run longer before needing new batteries) and have the same sound set on them.
