What are you measuring? How fast, amplitude, triggering requiremnts? Having used HP, LeCroy and TI. My least favorite is the LeCroy. Poor visibility of cursors, and trigger level. Flexible but challenging trigger modes. The acceleration & sampleing on the knobs is horrible, 1/2 the time, values go down when turning up due to slow knob sampling (aliasing). Works properly when it counts for critical measurement though. We also use an old HP logic analyser, old slow UI but easy to use and does the job.
