I right now own *everything* IKM (thanks GB),, including AXE I/O and iLoud MTMs, but the only MAX I actually own today is ST4MAX. And thus it's the only thing that may help me to get to Total Studio MAX 4 when it comes out. And even that will just more or less get me where I am today for "money for (almost) nothing" unless they introduce 4 new amp sims, 6 more synths, a slew of libs and some FX's. It'll probably cost me $499 to go TSM4 but I would finally be on the MAX train. <groans>
