even when 1102 is 100Mhz, the lowert price I understand that isn't better than 2072, but I don't know/saw what...
There is a huge difference between the DS1102E and a DS2072:
DS1102E - 100MHz, 2 Channels, 1GSa 1CH / 500MSa 2CH, 1M 1CH / 500K 2CH, 15-85 wfms/s ?, 5.6" 320x234, 2mV - 10V
DS2072 - 70MHz, 2 Channels, 2GSa 1CH / 1GSa 2CH, 14M 1CH / 7M 2CH, 56M 1CH / 28M 2CH Optional, 50K wfms/s, 8.0" 800x480, 500uV - 10V
To summarize, twice the sample rate, 14 to 56 times the memory, 500 times the waveform update speed, 42% larger screen, 5 times the pixels (384000 vs 74880), and lower vertical voltages (500uV, 1mV) assuming I have all this info right...
