Well i'm sold, can't wait for the QSX to be released so I can really start using my AE license! Thanks!
Before you do, if you have money available to throw at it, I'd probably go for a commercial rig first that can kick out 100W and start there. Yaesu FT-450D is the sort of thing that's a decent "first rig".
If you can't afford it, go for the QSX! I may replace my commercial rig with one if it's any good.
The SDR sure has utility but that comes at a compromise. I've done some professional RF stuff in the past and 99% of the problems are solved with very simple and way more precise gear compared to an SDR.
Have a look at http://websdr.org and have a play around with SDRs and then go look at a video for a Yaesu or Icom "rig" and see the difference in the usability. The QSX is more the Yaesu or Icom end of things.
