That Analog Devices AD9235-65 looks like it's good if you want to
sample at something like the USRP is doing right now - 64MHz.  So what
you'd be looking at is an oscope with a 500MHz bandwidth and a 64MSPS
sampling rate.  You could possibly double that if you did some
cascading of the ADCs and used the opposite edge of the clock to also
clock into a different ADC - giving you (effectively) double the
samples per second.

If one was to shift the second ADC by 90 degrees to the clock instead
of 180, wouldn't one be gaining I/Q data aswell as increase the
effective sampling rate?
