Necro posting 13 year old thread here because it is on topic and I don't believe in starting new threads unnecessarily.
And besides it might be interesting to see what folks are using after 13 years of technology changes.

The last linear power supply I owned was an Astron 35 Amp, but it along with a lot of other equipment got taken out by lightening strike on an 80 meter dipole that literally jump from the ladder line feed to the house mains and ran wild through the house.
That was around 2008, and while I planed on buying a new Astron linear supply when insurance paid off, I bought a Alinco DM-330MVT to hold me over till I got the dough for the Astron. The Alinco DM-330MVT was a new product at that time, it was made in Japan and the price was right so, despite warnings about switching power supplies causing receive harmonics, I gave it a try. In the end it worked so well I never bought a replacement linear supply. The Alinco has been rock solid and cleanly supplying a 100W HF rig without issue (about 22 Amps needed at full power).
This is a review from that era.
Mine is still good as new. Well with one exception that I just discovered this morning as a moved it to a new location. My cat Bridget has been chewing on the voltage adj/noise offset knobs, fortunately for me I had enabled a switch on the back to disable the knob and lock in 13.8V, and actually I have never needed the noise offset. It was out of sight and I never noticed what the little cat bastard had done.
ANYWAY... Cat damage is not why I am writing this morning; it is just an amusing aside. No the reason I am writing is my new power supply that arrived from HRO yesterday and naturally I want to show it off (wouldn't be a ham otherwise).
I decided I wanted to move the Alinco supply over to exclusively power my Yaesu FTM-100D VHF/UHF rig that it currently shared with the HF rig. So I was going to need a new power supply for the Icom IC-756 Pro III HF rig.
I could have bought another Alinco but I wanted something higher amperage rated.
So I decided to go with Astron and I decided to stick with a switching design supply. The Astron SS-50M-AP which is rated at 40 Amps continuous. Front panel has two power pole and two USB outputs. The rear has a pair of screw terminals where I attached a 10 AWG wire harness with power pole termination. Wire harness is actually one of these that I cut the solar system end off and save me the trouble of dragging out my power pole crimper and making my own.

I have yet to put it under load as I am rearranging the rats nest that is the shack wiring. We shall see as I will probably try and get on the air for the UBA CW contest today.
So what are you folks using for power supplies? Most folks still using linear designs or have switching supplies advanced to the point where folks trust them more? And as an aside, have MFJ power supplies continued their roll of the dice slide toward QC nightmares?
