> Would you recommend any stable and trustable power supply brand?  I need about 12-15V DC adjustable  and 15-20A at output.


What are you running with it?

For my ham gear, I use a 12V gel battery, and a 3A power supply which
is adjusted to the batterys float charge voltage.  The assumption is
that while I need >10A during transmit, I don't actually need to
transmit all that often.  I can do 50% duty cycle for several hours,
draining the battery, and the power supply refilling what it can while
I listen, and when I turn it off, the power supply completes the
battery charge.

Different solutions for different problems! :)
