Or buying the 100 Mhz version? Are you saying that either didn't meet advertised specs, or that neither was a good value? If you don't like Rigol scopes, buy Tek or Agilent or LeCroy. Of course, the low-end Agilent is actually a Rigol. They rebrand it and sell it for about twice the price of the Rigol. How do you like that for rip-off-ness? What kind of scope did you last buy? I got a Rigol 1052, and I'll probably buy a few more. John |
