I'm putting together a rig for a solo project, consisting of my Roland GR-55, the Pigtronix Looper, a TC Helicon Voicelive 3 vocal harmony / effects unit, and a Beatbuddy pedal-format drum machine. I found a great deal on Reverb for a like-new, light studio use only, Infinity plus auxiliary pedal ($350 shipped for the pair), and it arrived today. I just spent my first few minutes with it, and I really like it so far. I just gave it a basic run-through, recording a couple of loops and overdubs, plus having great fun with the 'reverse' function. It's very solidly built, functions perfectly, and the controls and operations are pretty intuitive for not-very-experienced-with-loopers me. One of the reasons I chose this one was the midi-sync, which I'm expecting to mesh well with the Beatbuddy. It will be a bit longer before I can check that out, though. Another big reason is that in watching the videos for the popular advanced loopers, this was the one that made the most sense to me. I'll be diving into more advanced use as the days roll by. Happy to have it, and more thanpleased so far.
