Yes, if you use a condenser mic that needs 48V phantom power and you have nothing that can give it, you need an audio/interface that will, and also MIDI if you use that. Check the Sweetwater link I gave, just to look around, quite a few for about $100 to $140, so I really do not know what that is in pounds around what - say 50 to 75?? If you buy no Channel Strips, or anything else, than you will need all of that on the audio/interface and I have seen some there listed at Sweetwater (not the only place to buy) for around $150. Also the one you were looking at is on $79 but a better one is $99 from Roland. Drivers are very important for Windows 8, because like a sound card in the computer it needs drivers (especially ASIO) for recording and listening. ASIO4All is what some use, but that is a generic driver not as good as a dedicated driver usually by the manufacturer of the unit you may buy, so make sure the drivers really work, some do not work as good, and the ones that do were mentioned in another post. I don't really know but look up Beagle here and review his website pages on it also. (or ask him also)
