    Hi All-

    I am looking to buy the best benchtop power supply that I can get for around $150. I am looking for an adjustable supply from around 0 - 30 Volts and 0 - 3 Amps. Dual output would be nice, but isn't required. I see a lot of off-brand ones on eBay, but I'm skeptical of those. Any suggestions?

    It helps to know where you are from. I have the CS13303S from Circuit Specialists that has suited my needs but I think they only sell inside the Unites States. Pretty sure I paid less than $150. I am sure it is someone eles's power supply with their brand but it works just fine.

    Check out Mastech for new power supplies..
    If you are looking quality then I would buy a used one within your price range.

    I always suggest a three output power supply. One to go from 0-6V @ ~2A and another variable from 0 to +/-18V @ ~1A. Three power supplies are very powerful. They allow you to power your logic and your analog signals without having to jump through too many hoops.

    If you're a hobbyist I always suggest you build your own power supply. Much cheaper, but more time consuming, but you learn SOOOO much about electronics when you break open this project. It's usually a 1-3 month project. Dave Jones at EEVBlog has a good 3 or 4 part series on making a adjustable power supply with the LT3080 - Excellent stuff - but his voice is annoying as hell - but he certainly has a passion for teaching and is good at it.

    If you're a professional just buy a power supply... you need to be up and running more than anything else. Any off brand power supply should do... if it fails just by another.

    If you just want 3v, 5V, and 12v, an old atx psu is an excellent bench psu, at high current and good regulation

    Excellent advice. I have been watching that series. I think I will try it.

    Thanks to all for your comments.

    I couldn't bring myself to watch it. Tried skipping around to see if there was any useful information, but the Guys voice is like fingernails on a chalkboard to me...
