USB DSO aka PC oscilloscope recomendations

[Michael Hill]

I'll agree...you really do get what you pay for. 20MHz is pretty trash for an oscilloscope, and don't bother with the salaea unless you need a logic analyzer. Having the mixed signal analysis capabilities can be very useful, only need analog capabilities, the Rigol's the way to go. I bought my 50 MHz one only because I knew I could mod it to have 100 MHz capability. An alternate solution is to check out local university surplus sales. Sometimes they have scopes in there for real cheap.
