I have had an ETX125 for several years now, and it has run quite happily off a 500mA supply, though thats right on the limit at times
The ETX125, when slewing full speed in one axis draws about 250mA
and in both axes at the same time, about 480mA
Normal tracking operation draws about 80-100mA
The 800mA unit nightsky has bought will be OK.
( I still wouldnt have bought that one though )
I do agree a larger capacity plugpack for more accessories is a nice option, but in that case, you would really need to get one with banana plug outlets, or connecting the extra cables is going to be a pain.
I note the GH1379 appears to have a specialised connector, so he would have to cut this off to fit the correct 2.5mm DC plug anyway.
Whilst more expensive, the Desktop Regulated units MP3017 or 3434
look like a more flexible bet. Or even better, the MP3035, as it covers a more usable set of voltages than the MP3034
Lastly, i have been playing with testing dewheaters for RFI recently.
As a side effect of this, i "heard" the difference between switchmode and Transformer type plugpacks.
Whilst the switchmode units are much lighter,
they are more likely to fail when their capacitors blow.
( I now have two like this )
and they also put out a "lot" more RFI than the transformer units.
The latter hasnt affected my scope to date, but you never know.
