I do a LOT of iPad recording with Auria and other apps, it's a very cool platform to make music on for sure. The Line6 TonePort is a great device, I still go straight from my acoustic pedal board to my DA, but I know a few people using those who love them. I've owned pretty much all of the Line6 Pods over the years, and they all sound great. I don't think you'd go wrong with that at all.
