I bought my Helix about a year ago and have been more than happy with this unit. Great interface, wonderful sound quality and the updates keep rolling out. Definitely a quality product. 
  
I had a problem with a single patch that would cause it to freeze, every time. I sent the patch to the customer service department and was assured it was a hardware issue. From there on I can't tell you how impressed I am with the service that followed. They went out of their way to give me the best service I have ever received from any company in the music business. I've been around a while and dealt with many companies over the years but nothing comes close to what I experienced with their exemplary customer support. Will was the representative I had the pleasure of dealing with. 
  
Thank you Line 6, you have a customer for life!
