ok great thank you! im still really on the fence about sound, so what i think i'll do is just go ahead with the li ion setup (per everyone's recommendations!) and just worry about the sound at a later date.
i know many of you may still not understand but keep in mind, i plan on purchasing two of whatever saber i decide on so my costs are double what you'd normally expect.
anyway, thanks everyone that replied, i do appreciate it!
getting sound later would also be an additional cost and be more tham waiting and getting it initialy???
