However, the reason I want to debunk the need of a power supply from R&S is from the point of view of single person/engineer with a lab. at home and limited budget compare to a company.
For the price of a NGE103b, I can get a mid-quality but decent power supply (that will do its job) for less money; which will leave my wallet with extra cash to get more equipment.
What I'm looking for is to learn from experiences from colleagues that had experienced this dilemma before
As a hobbyist (with a limited budget), I understand completely
I have quite a few (non-R&S) "budget" power supplies that I use for my hobbies when I don't have one of my "work" power supplies in the office.
I always say one of the best parts of my job is that I get to borrow equipment that I could never afford to buy with my own money
