VK5RC:
On 'fleabay'  the 3721 goes for about $900.

nctnico:
I got mine through Ebay as well. I can sum up the the software which comes with the dummy loads with two words: useless crap.

HighVoltage:
I have a BK Precision 8500 and a Maynuo 9811
And I can highly recommend any one of those two instruments.
Somehow, I like the Maynuo a little more, because it has 2 lines and 4 numbers at the same time in the display.
So, watching voltage, current and power at the same time, is sometimes a little benefit
And the software on both systems works great.

For a lower end project, I needed a low cost solution and ended up with several 100 W power resistor, instead of a DC load.
Because I did not like the lower cost units at all.


Circuitous:
I have a couple of Array loads, 3723A and 3710A.  I like that they can display 4 attributes at once (unlike the BK) but the PC software isn't great and it has a crappy TTL interface (not RS-232 or USB) that requires an adapter (you can make your own).

The backlit LCD on the 3723A is clear and bright, easy enough for me to read from 3 feet away. But, I still would prefer a VFD.

If I was starting over, I'd probably get the Maynuo.  I may pick up a M98xx later this year.

The 3723A has an isolated, true RS-232 inteface.  No adapter needed.
