Should I go portable?
I've already bought a Focusrite Scarlett 18i20 (4 preamps and USB) for £250 off amazon. I am still within my return window. Should I instead return that and get a Focusrite Saffire Pro 40, second hand, off eBay for around £200, although it works out at around the same price due to the cost of a FireWire cable and the £25 FireWire to Thunderbolt adapter?
