I realise I don't know your location, but the price of the PSU you mention at Farnell is £216... and I was trying to figure out why it was so much better than the one I bought from Maplin (**broken link removed**) which has served me really well for a couple of years (I'm only into the most basic stuff) but then I noticed the price of this from Maplin was £85 and that really shocked me, 'cos I didn't pay £85 for it, I paid £29.99... so I must've have fell upon an amazing offer they were running at the time.
I'd still very much like to know what is so much better with the PSU you provide a link for, as opposed to the budget Maplin one. Just for my own curiosity and education, you understand? Is it build quality, is it features? I can see that it has lots of buttons, but I am - as yet - struggling to understand what they might all be for... (I Googled a picture of it and I can see them all now... some do look really superfluous)
Setting the voltage very specifically can be quite hard on my PSU - steady hand - but once it's set it's fine.
