Dude, I wasn't a fan of batteries either, but trust me, once I got the preamp.... I NEVER looked back. Now, I won't buy a bass without one. The reason people say they deplete batteries too quickly is (1) they use ACTIVE pickups with the preamp (active pickups use batteries as well, so twice the consumption) and (2) they leave the bass plugged in. Pretty much every preamp turns on when it's plugged in and off when it's not. Plus, changing batteries in new basses is easy. I got my preamp like 5 months ago and I play for HOURS everyday, still runs on the same battery. I have another bass the uses one too and the preamps are just indispensable.
BTW, you won't need to refret your bass. I bend ALL THE TIME and mine are still good. And if you use flatwound strings, then fret wear will be almost nonexistent.
