I love the TK17-R Kalimba!
Such a calming instrument to play. The tone is held for a surprisingly long time and it plays louder than you'd think - It fills the room!
Pros: Durable, clean tone, intuitive to play.
Cons; Needs tuning as frequently as a guitar - But hey, it's an instrument!
Pro tip; You can use any kind of tuner for it! And you can put a piezo mic inside of it to get a real clean recording of it (Or just use a regular microphone, you do you...)
