content: Korad ka3305d or ka3305p. Mine works quite well. And 3 channels are useful

content: KORAD KA3005D has capacitor on the output, so it has some issues with current stabilization. But this is really best middle class PSU.

content: I think that most of the psu in this price range has some capacitance at the output. Need only to be careful to always use the turn on/off function instead of live connecting the things. There can be some problems also on repentine current draw changes

content: OP should first specify required number of channels, output voltage (range) and power, and if the acceptable amount of output noise will permit a switcher. After that, suggestions make sense and could possibly lead in a different direction...

content: I like this better than the Korad, but I tend to be an odd duckSIGLENT SPD1000X Series Programmable DC Power SupplyOnly single channel, but very precise and ultra low ripple.Available in 2 varieties:SPD1168X: 16 V / 8 A，total power up to 128 WSPD1305X: 30 V / 5 A，total power up to 150 WHas 5 digit Voltage, 4 digit Current Display, Minimum Resolution: 1 mV/1 mAI think it looks sharp on the bench with it's color LCD display.I already have a 3 channel boat anchor, so I have my eye on this and other similar products, so thought I would share. It's great if you don't need multiple channels.

content: What you guys are suggesting, reduce the price tag to about 33% to 50%, as India will put quite a hefty import tax for such merchandise, guess where did I learn that.So, for $250 budget, if imported, then the realistic price that we're going to suggest maybe about $75 to $100 price level of merchandise.
