Wow - thanks for all the responses! I bought the HammerSmith before all of these, here's my impressions.
Keep in mind - this is the light version...
1. It takes are really long time to load. My computer isn't the fastest in the world, but I've never had a problem. I have some EWQL instruments, some Heavyocity instruments and Omnisphere and they all load MUCH faster. Might be something with my system, but that was my first impression... 30 seconds to a minute... Uses about .58mb of RAM.
2. It sounds great! I immediately loved the way it played. The room mics are awesome. I've been using the stripped down version of Addictive Keys (the one that came preloaded with Sonar when I bought it a few years ago) and this sounds much better!
@emeraldsoul - I still need to hear how it sounds in a mix. I don't have the familiarity with Steinway or Yamaha enough to have a preference - but I immediately recognized that this sounded different than the C7 at the school where I work. In my home, I have a Yamaha upright.
All in all - I think it was definitely worth the $57 I paid! It was the right price point for me... And well worth every penny.
