I have the Crescendo. Traded in my Symphony for it for several reasons
1 - needle threader. No lever, just push a button.
2 - lighting. As we age (I'm now 75 ) we need more light. Superb lighting.
3 - walking foot. Great foot , super easy to install, and the needle threader works when it is on.
Since I got it, I've been using the laser. Didn't think I would, but it's a great feature too. Best thing I did was to get it. Sees beautifully, too. Love it love it love it!!!!
Go for it. You won't be sorry.
