Assuming you want a 5Mhz "Bandwidth". Which way do you mean?
5Mhz bandwidth? Or 5M samples/sec?

When I say x5 -- I generally mean that, if you consider 100MHz to be your highest point of measurement, then ideally you'd probably be best of with a 500MHz scope. I think though however, this old saying is more applicable to analogue scopes than anything.

5MHz bandwidth for a DIY scope? -- personally, I'd be chasing 20M samples / second or more.
