Hey all, I've just seen Producer X1 online at a good price (£150). I was aiming to get Producer Suite but It's too expensive, and I won't be able to get the money before Christmas. I'm wondering whether this will allow me to upgrade to Sonar X2 Producer for free? (Regardless of who I buy it from?).

Yes, it does not matter where you buy X1. You need to register X1 before the end of the year to qualify for the free upgrade to X2.
