If you want to wait until a make & model comes out that has zero problems in the field, you are going to wait forever.
I'm not sure why you're hell-bent on getting a new power supply over a used one. Depending on your current needs --both amperage & timeframe-- there are plenty of very inexpensive supplies on eBay that work just fine. I have bought two supplies on eBay, both of which said "Not working, for parts" and after reading the description I decided that I would pay $15 and try my luck. In both cases I won the auctions and got supplies that work JUST FINE but have either a small cosmetic issue or simply weren't tested by the seller. One is an HP 6286A, 0-20V, 0-10A, the other is a Power Designs 3650-S, 0-36V, 0-5A. I designed a 3D printed a meter clip for the HP at home, printed it at work, and I adjust the voltage & current on the Power Designs supply with a multimeter connected. Solved, for $100 total in purchase price and shipping, and I now have two excellent supplies.
I also have a Rigol DP832 that works great. Yeah, you need to wire output 2 & 3 ground terminals together externally. Yeah, there's a small output spike on each channel, but they are so short and have so little "oomph" behind them that I don't worry about it a lot. I'm aware of it, though, and when I am doing work where a short small spike would cause damage, I just won't use that supply or I'll put a tiny cap in series or something. As long as you KNOW the problem(s) that your supply has, it doesn't matter what the problems are.
Knowing the problems and knowing when/how to deal with them is far more important and far easier than finding a supply with no problems.
