Personally I would get the 110e, in case you ever want to plug in. To my knowledge, the only difference between the two is the 110 is straight acoustic and the 110e is acoustic/electric, so they should sound the same unplugged.
well, acoustic is fine. just as long as you have a microphone to it. you should be able to hear it.
The main trouble you'll run into is if there are any electric tricks that can't be done on acoustic, because it involves doing something that sounds great through an amp. You may not recognize what's not possible on an acoustic. But except for those ...
