I'd be interested in hearing if that unit has RFI problems. I had one
that looked identical to that, with the brand "Jetstream" on it, on a
spectrum analyzer a day or two ago. Appeared to produce lots of RF
hash. Might be OK across a battery, but looked really bad by itself
(hash at -80 dBm or so). The hash was riding the power cord as well as
the output terminals. Did not do a through check, not enough time, just
a quick look.
In comparison, my MFJ-4125 produces no detectable hash. The spectrum
analyzer has a floor of about -100 dBm so there could be noise below
that that I'd not see.
Usual disclaimer . . . no interest in either . . . just wanting to know
what is going on . . . .

It's about the same size at the MFJ-4125, and W&S may have a better
reputation than MFJ.
It does look like a nice piece of kit, but what kind of warranty
coverage does W&S give to non-resident purchasers?
The price is very good, in fact, especially if W&S will do the required
paper work for a VAT refund.

On the PSU - why not buy one here (I guess exchange rate might be an issue),
I'm using a Watson Power-Mite, purchased from Walters & Stanton (Watson is
their kit)
http://www.wsplc.com/acatalog/Watson_Mains_Power_Supplies.html
should be the first item on that page
Its very small, quiet - both physical and appears to be on RF too
Has switchable input voltage, so when you take it back it will work - it
should work in any country I would have thought.
A few nice features:
* uses a standard power cord with 'normal' PC style 3 pin - just take the
right cord for the country (anyone know right code for that kind of plug).
* fan can run in auto mode or permanent on, it didn't come on much when I
used it with my FT-857 in the summer.
* short-circuit and over-voltage protection
* adjustable voltage, so if you don't really need another supply at home,
use it on the bench etc.
since you're staying with family, have it delivered to them or get them to
purchase for you, W&S have a shop in the Midlands and Scotland too.
I haven't used the Alinco one, but it has an adjustment to compensate for
the RF it produces.
