Comparing it to the other machines I am familiar with--the Janome MC6600, Elna 7300 & Janome Horizon 7700--it does look like a good deal to me but I am not familiar with the Silver brand. I would do a google search for reviews and see what others who own Silvers have to say.
My Singer has about a 6" throat and my Elna has 9". That is a big difference when you're trying to paper piece, add large or mitered borders, quilting or thread painting.
