I picked up an IB318 in late 2011 to play with, thinking I would buy another one if I liked it. Well before I got around to picking up my second one they were discontinued for a while. I'm wondering if, for home use, if I buy a second IB318 now if the current TS specs are close enough to the previous model to just use the two of them together? If not does anyone have the TS specs for the old ones or any idea what would be the best route to take as far as figuring out what to do with the one I have or how to get a matching pair?
