how to buy an oscilloscope

To be able to display oscilloscope music properly, it needs:

- CRT screen ⇒ analog ⇒ they aren't built anymore, so get a used one
- XY-mode ⇒ 2 channels, XY button
- able to display frequencies up to 100kHz ⇒ they all can
- fully working ⇒ check description
- price: less than $100 is cheap, less than $200 is ok for a fully tested device
