I know theres not much love for the cheap import stuff in this thread, but i have this one, and its been verrry good to me for the price:
Tekpower TP3005T Variable Linear DC Power Supply, 0-30V @ 0-5A with Alligator Test Leads (110V Input) https://www.amazon.com/dp/B00ZBCLJSY/ref=cm_sw_r_cp_api_S9nYBb4J9SGFW
All of the "cheap" $50~$100 bench supplies that are on Amazon are the same quality and probably come from the same factory in China.
One level up are Siglent and Rigol $300~$600 which can be found on Amazon.
I have a Tekpower ~$80 that is ok Amazon link.
