Where can I get a 5V 3A Neo PSU? (Pref in the UK)

I need a couple of 5V 3A power supplies for some Pro-Pow AES's and just wondered if anyone had seen some cheap unofficial PSU's that would do, preferably with a UK plug. I tried maplin.co.uk but couldn't see anything. I don't want to have to pay the silly money people ask for Japanese Neo PSU's.

Also, would these work?

2A is a bit on the low side but it would probably work anyway. The problem is that the polarity of the plug is positive inside and negative outside (by far the most common option) while the Neo requires the opposite. Actually this parameter is hardly ever fulfilled: you can easily find PSUs with the right specs except for that. For instance all these PSUs would work but the polarity info is not given and I doubt it will be the right one for the Neo.

It's not difficult to invert the polarity of the plug by either internal rewiring or plug replacement but it requires soldering...

My buddy & I hooked a meter up to an English AES the other day. It only displayed a draw of 1.15 or 1.5 amps, so a 2 amp PSU should work.

So would the Lik Sang one not work because of the polarity or would it work but be risky?
I wouldn't attempt to re-wire btw I'm useless with a soldering iron ;)

What about this?

AC input (100-240V) is OK
DC output (5V/3A) is OK
Plug size (2.1mm x 2.5mm) is OK

As for the plug polarity, the info is reported on the label but it's too small and I can't read it. Considering the brand is Meanwell my guess is that it's incorrect for the Neo as all Meanwell PSUs are positive inside.

Thanks for the help :)
Turns out I might not need one for the time being as I've discovered one of the Pro-Pow's I have is a freak and doesn't work with 5v but works with 9v :rolleyes:
