Can any one recommend a good but affordable power suppy

I have been looking for a good, low-cost, dual channel power supply. Ideally I would like variable voltage (0-30V), current limiting and good current reporting (nice to be able to see uA level readings). Anyone have any recommendations?

Thanks!

I use a Tenama, its not the best but it sure does the job. Kas

Although I've never used it, Dave Jones makes a uCurrent adapter for multimeters https://www.eevblog.com/projects/ucurrent/

Yeah, that is pretty cool. I have seen a couple of write-up on this product before. I have used a ACS712 (Hall effect, linear current sensor) in another product and I might be able to adapt my design slightly…

Thanks for all the good recommendations!
Thanks to jw0752 and @Michael Wylie for the suggestion to use an external ammeter as a way to get better current resolutions. I have tried this in the past with my cheap multimeter with less that stellar results. Now it looks like I need and new power supply and a new multimeter!

I have used a ACS712 (Hall effect, linear current sensor) in another product and I might be able to adapt my design slightly to build a suitable current monitor (hopefully with a gain selector to allow current ranges). I just have to either find some extra time or extra money (it always seems to come down to one of the two).

Thanks!
