You got me curious, and I wondered what alternatives could be.

I found this interesting stack overflow answer:

https://electronics.stackexchange.com/questions/3206/best-so...

unfortunately the question was closed:

  Closed. This question is opinion-based. It is not currently accepting answers.

Annoying that stack overflow specifically shuts this stuff down.

Shutting down discussion makes it seem like a self-serving answer mill instead of a community.
