This is very cool, but very expensive. For this money (€230 in EU) there are a lot of other options, however, for getting an oscilloscope that is useful and robust (unlike those €30 DIY kits that ... I'm too clumsy not to break).
Yea, you can get a Rigol or Siglent 2-4 channel oscilloscope for barely much more in the $300-5000 range. I guess it's neat because of its size, but there are other options even cheaper than the Rigol and Siglent ones.
Do either of these have pitch detection?
If by pitch detection you mean fundamental frequency measurement for a given channel, then yes, and much more.
