We have all manner of oscilloscopes in the teaching labs where I'm currently working, and the one thing that separates the Tek, Agilent and LeCroy, from the Digimess, Owon, Rigol, Tenma, is their ability to properly band-limit signals before sampling them and displaying them. Some of the cheap Chinese copycat models will quite happily show you a 20MHz signal as a 1kHz signal if you have the timebase set to 100us/div.
