Thank you for the nice words :-)
The mellow sound of the Tenor is why I chose it. Also for the ability to use a lower string for the top one (low G instead of high G). This allows me to play "Somewhere Over the Rainbow" with the bass line.
If you just want to explore, plastic or wooden does not matter. If you think you will get into it more seriously, you better choose solid wood or at least solid top ukulele as this will produce a much nicer sound. Bass ukulele are pretty cool indeed.
No pb, when you're ready, just ask me.
