Yes, the Lanikai bass is standard tuning. From all the options that are available now, I think I'd go for the Lanikai: Slightly longer scale, but still playable and small, nice looking wood options, and just overall pleasingly designed.
I have one of the very first U-Basses made by Kala. I love it, but I hardly ever play it. It's great for trying bass lines, and cool to have such a portable option for adding depth when playing along with others, but playing the bass by myself doesn't fulfill me. I know there are some great virtuoso bass players that are interesting to listen to and watch, but that isn't where I'm at.
