Other than the LCD display, is the 8753ES any ¡°lesser¡± of a VNA than a similarly outfitted ¡°D¡±? I ask because it seems that many ES¡¯s go for less money than the ¡°D¡±s. is this just a fluke of a lot of supply of the ESs? Any thoughts on this?
Thanks

Not that I am aware of. The ES has the advantage that there are 4 buttons for switching channels. It also takes later firmware, and I suspect that means it has a later (faster) CPU.
Now I don't know what difference there is between an 8753E and an 8753ES. That might be worth investigating more, but i would certainly not buy a D unless it was a lot cheaper than an E or ES.
Despite the extra bulk, I'd buy one with an external test set, as it gives you a lot more flexibility. Note the 6 GHz option on the D/E/ES are all hardware, so you can't easily upgrade them.
