Alright, I've searched previous threads, but they seem vacant and dead.

I was looking to the LC-100 (entry level model), and when I played one at GC, it didn't entice me.
Now the LCT250CE, that was more my speed. One of the things I'm worried about is having to replace the pre-amp battery. The pre-amp is not a neccessity for me, as I just want an unplugged jam guitar to carry around town with me and for making compositions/writing. But if it has that feature, there's no sense in not using it.

My question is 2-pronged; are there any upper-tier Lucero models and how do I go about replacing the battery?
