I have run the SAMLEX 1223 (branded as the YAESU FP-1023) for a few years without a problem.  Its plain Jane, but it works.

If you can afford it, get a 30 or 35 amp supply . Sooner or later you will want a second radio, and a couple of mobile rigs in the shack for 220 or 900 mhz and so on. if you can pick up a good used 50 amp suppley  it will handle your radio and even a small amplifier for 2m or such.  but at least get something at 25 amps or better, as a 100 watt radio will draw 22-23 amps on tx.

I might get blasted for this one, but I have been using a Mega-Watt 30 amp continuous switching supply for over a year now with no problems.
Mega-Watt power supplies are sold in the USA by:

Assessment with an oscilloscope that can SHOW AC ripple on DC output is a USEFUL Test (results), as well as regulation measurements (voltage sag) under rated loads (Amps).

I was going to suggest a battery with a 13v small power supply to charge it, but $50 for a 30A supply is a real good deal.  You'd have to be buying batteries once in a while too, but it does mean you can work when the power is off.

Shipping is reasonable too.

Buy nice, not twice!

get a good brand, and don't skimp on size.

Switchers are lighter if you need portability but can cause noise on some bands.

Linears are heavy, not very portble, but RF Quiet.

What do you need it for?

Where are you going to use it?

How many Amps do you need?

Check with club members, often someone has an old linear around gatering dust, may be just what you need.

The question reminded me of the TV commercial where the guy was driving down the road with a cloud of black smoke coming out the tail pipe.  When a passenger asked him what kind of oil he was using, the replied, "Oil? No idea.  Oil is oil!"

Going "cheap" on a power supply for an expensive transceiver is exactly the same and quite possibly with the same result..... a lot of back smoke being released.

I also like the Samlex (23 amp).  Fan isn't noisy and although it is a switching supply it causes no RFI/noise here in my shack.

I've got an Alinco DM-330MV that's been running more-or-less continuously since when I bought it new in 2005.  It powers my Kenwood TS-2000, Yaesu FT-8900, police scanner and XM satellite radio.  Solid DC output, small form, lightweight, RF quiet.  It just keeps going and going!

  I like the Alinco DM335.  It has the meter, jacks front and rear and a place for a cigarette lighter.  This makes this unit quite versatile.    The Samlex is probably cheaper.

I like the Astron 35 amp supplies. They are reliable, quiet, have crowbar protection to save expensive radios, and are easy to repair in the rare instance something does go wrong. They are not as efficient as a switcher but they sure do last.

Another fan of the Samlex SEC 1223 here.  I have used these on multiple 100W rigs of various brands with nary a problem.  Inexpensive and light weight, with no noticable noise, audible or electrical.  They have current limiting, short circuit protection and over-voltage protection.  Be sure to get something that has at least 23A capability, since some 100W rigs go right up to 22A or so (and a 20A supply won't cut it).  They are great!
