in all honesty i don’t want to build any kind of power supply. money’s not an issue, i just need something that’ll do the job with the least footprint and hassle. will this, http://www.ebay.co.uk/itm/250977147988, not cut it?
Theoretically it cuts it, based on the power requirement, not sure if it is got quality at that price. Maybe you would better use a metal house power supply (preferably potted) not a thick plastic one that is made for travel? I am thinking about the capacitors quality and the heat they are enduring or not.
You may want to try the 12V 80W power supply from this seller, or even 12V 50W if you are ok with it, there's no problem

to be honest, i was looking at this as well and you’re right, it does seem to be of better quality! thanks for all your advice, it’s really helped!
