The AGA-T2 is a classic, bread n butter for newbie and veterans alike. It is harder to set up than the RSST,which has insulated contact points, but it is like most of the other RBAs. Hence, you can choose either to go with the RSST for a quick and easy setup, or the AGA-T2 and go through the steep learning curve of RBAs. I always recommend the latter: it can be a pain to learn, but once you do, you know how to set up all RBAs.
