Emerson Flute Question

[Twifilldr]

I began playing flute about 26 years ago and at the time purchased a used Yamaha 24N. I am looking now to upgrade to something a bit better and have found a used Emerson. Seller is telling me the model is Emerson Soloist, S/N is 50325. If what I've read is correct that would mean it's made in 2000. Sterling silver head joint, silver plated body, gold mouthpiece. It's been gone over and is in good working order I'm told, and I can return it if it isn't. it's open hole, offset G, B foot with gizmo key. I'm wondering if anyone can tell me something about this flute and what it may be worth. I've had a heck of a time finding info on Emerson, and even the Conn-Selmer website has nothing. Some folks seem to love them, others hate them, and I'm clueless. I'm looking for a decent upgrade to what I'm playing now. Sellers's looking for 700 and I'm wondering if that's reasonable for a good intermediate flute almost 20 years old? Thanks
