What multimeter you buy is up to you. All I'm saying is that people should give an unknown brand a try. Chances are that equipment for Tektronix, Agilent, Lecroy, etc is rolling of the same production line or designed by the same people. Anyway, I've taken some pictures of the inside of my VC8145:
The rear with the 'RS232' interface, power supply and transformer
The front:
A close-up of the inputs. I like the inputs bushes are not soldered onto the PCB but use screws (with a spring washer). Soldered bushes often give problems in the long run.
An overview of the display board with a Holtec 8 bit microcontroller and what seems to be a display controller:
The 'RS232' plug on the back seems to be isolated after all.
Here is the analog board without the shielding:
On the analog board there are several hybrid resistor ladders, a special chip and some regular stuff like an LM385 1% reference and a 12bit DAC. The DAC is interesting because it is relatively expensive costing more than $5 even when bought in large quantities. The designers clearly didn't cut a corner here.
Furthermore there are some relays from Omron and two HC4053 analog muxes from ST
