I went from the espire(one before the symphony) to the dreamweaver combo(unity for babylock). I think you would get more money for a private sell personally. I do think the difference in the machine is worth it IMHO the crescendo has so much more features and the muvit foot alone is worth it even without the laser. I do like the laser though as well and I am looking forward to using it on HST soon. I love love my machine and don't regret my decision 2 years ago. I just regret not waiting a little longer and getting a better deal off of the price because even though I got more than my machine was worth, I got it off MSRP so still paid more than if I had waited for a sale, but I still love my machine and did get approximately 3000 dollars for my espire so I can't really complain since I paid 1800 for it. I think 1000 is not enough for your symphony as you could probably sell it for 12-1500 privately as they still cost anywhere from 18-2200 depending on your region
