I Have a GPD-4303S, the four channel version. It's a nice unit, four channels on a relative small footprint. There were some issues in early models having overshoot in channel 3 and/or 4, can't remember exactly but that info is on this forum.
I did measurements on my unit and did not see any overshoot, all channels spot on. So could be I have a later revision.
Also it has one "output on" button for all channels, so all go on at the same time.
If you want to know more details, please ask.

i love the GPD-3303S supply!!!

pretty much flawless, and bulletproof.  I've used and abused it a lot. and.. never seen any issues like described above, no overshoot etc.
has fine and corse digital voltage and current adjustments. basically does it all, even has a usb interface and compatible with labview.. things i'll never use..

i picked one up when the ITT school supplies were being blown out on EBAY for 100 bucks.
SADLY, no such great deals today, but still they can be had off eBay for around 200 bucks.

considering they retail for 500 bucks, that's not a bad deal.  i'm keeping an eye out for a great deal to nab a second one
