content: HiIs the ATTEN APS3003S-3D any good, anyone have one and can comment?http://www.triosmartcal.com.au/dc-bench-supplies/2432-atten-aps3003s-3d-dual-power-supply-0-30v-3a.htmlOr would I be better getting two of these:http://www.triosmartcal.com.au/2647-ka3005p-programmable-dc-power-supply.htmlThis for a hobbyist. I was hoping to get a supply that has a fix 5V output and one variable output for small projects.Thanks for any advice.RegardsDaniel

content: i have an atten APS3005S, seems alright.bk has a variable with fixed 12 and 5 volt outputs on it.the atten or mastech triple output look good. lots of options with those.

content: I have a similar supply from Circuit Specialists that's a rebranded Atten. I also have a crummy programmable supply from Quakko (yeah should have known from the name) that's a bit like Korad you list.One thing to watch for when using these low end supplies is that they often have a voltage surge on startup. If your circuit is connected when you switch on the supply, you can fry your device. This is a very common problem in low end PSUs.This even happens with the Quakko PSU, which has an output switch... just power up the supply (comes up with the output turned off) and watch the surge on the output. Really bad design.Here's a discussion and teardown of the APS3003S from an earlier thread:https://www.eevblog.com/forum/reviews/atten-aps3003s3005s-variable-power-supply-review-and-teardown/

content: I have the same re branded CircuitSpecialists .. decent. The fan does sound like an airplane and is annoying the heck out of mebut in rest the supply is OK. It does not look or work bad overall.I am working to put a fan controller with a good fan and replace the cheap Chinese airplane propeller ... just did not had time to get to finishing it and put a small additional board in (there is plenty of space in the case). Also i think having multiturn pots won't hurt because voltage changes are .. the issue is to find small enough multiturn pots that fit right in to replace the existing ones.BTW ... old lesson ... never power a project by just turning on the bench supply. Based on Murphy's law in 95% of the cases it will result in smoke ... the rest of 5% it will also catch fire. So be smart .. put an on/off switch on your circuit.
