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…

I am looking for a dual output, 1A and +/-15V as the minimum. Thanks for asking.

uAmps won't be doable cheaply unless you route through an external ammeter. I have used these two units and they are OK. If I recall correctly, they are heavy.

Kas mentioned a Tenma and Newark has one that looks like it is made by the same factory that made mine.
