I have a DP832 for a few years now, and it's OK. Can be unlocked and turned into a DP832A.
Not perfect, a few times the SCPI frozen and once it rebooted itself after a few hours at 2x3.2A and about 13V (so at less than 100W load). Don't know what it was, and since then never rebooted itself. It's very easy to use it as a simple power supply, but making it to output some test patterns is very cumbersome to set, almost unusable even after reading the manual.
Sometimes I find myself avoiding the DP832, and use brickwall power adapters, or some other diy power sources simply because I don't like instruments with fan. DP832 fan is not unbearable noisy on the first level (the fan has 2 speeds) but at full speed, in a quiet room, the DP832 fan becomes annoying.
Overall, I don't regret buying it, was a good power supply so far, full of features, comes in handy very often.
If it were to buy again, I would put some more money and buy a 4 quadrant power supply, or at least a 2 quadrant one (that can either source or sink current, so it can be used either as a power source or as a controlled load). For some reason, the need of a controlled load keeps popping up to me, and not only for battery testing.
