Currently I'm a married mother of 3, who now works in a hospital lab. I played flute in middle school/high school. Was in a pretty good band, I was a natural at the flute. Never had much formal training, but I did well in local and state honor bands.... though while I liked it a lot, I wasn't driven enough to continue in college, though now I'm wishing I did! I think sometimes people who a certain thing come easy to them, they aren't the ones who have the drive/stamina/desire to see it through.
I've played my flute throughout the years (graduated hs in 94), joined a community band for a while, but now I'm really getting back into it with a professional teacher. I'm ready for a step up flute. My goal is to play for fun, and then perhaps perform in any way possible. I know I'll never be a professional, but I'm hoping there's something locally for a dedicated advanced intermediate who wants to be challenged. Solo perfomances? Small woodwind groups? Community orchestras? The small community band was fun, but very un-challenging.
I currently have a Solid Silver Gemeinhardt KG Special, from about '90/'91. Model number 83738. I was so proud of this flute, as I saved up and paid for half of it. That's a lot for a sophomore in high school.

I've done my homework, and I understand that it's the head joint that is really important, so I'm on the hunt for a "relatively" inexpensive professional/intermediate flute for now, and then I'll save up for a better head joint down the road.
Here's my list below. My goal is to be under $2000. But I'll probably end up stretching that a bit, as seems to happen with most of my budgets in life.

Altus 807
Azumi 3000
DiMedici 1011
Di Zhao 700
Muramatsu EX (BIG budget stretch)
Trevor James Cantabile
I'm going to contact a place like FluteWorld.com to try some of these out. But I'd like any tips, or advice, or suggestions, knowing the flute I've come from, my background and knowing my goals above. Any other sites you suggest that will send you flutes to try? Do you have a favorite? Any offer a payment plan or a kind of a rent to own?
As a side note (totally wishful thinking), I'm hoping to maybe find a small flute business that would be happy to barter partially for some web design work. I am also a web designer on the side, specializing in setting up shopping carts (along with logo/graphics work), and the thought that maybe I could spring for a slightly fancier flute by working some of it off really sounds wonderful. If anyone knows of any small companies that need a nice web site, I'd love to know about them.
I'd also like some advice on how much I might be able to get for my used flute. It's in good condition, small surface scratches, no tarnishing, no dents, has the gold lip plate, and b foot. Pads were changed about 3 years ago, I think they are in good condition.
So I know this rambling, but my main questions are:
1) what do you think of my list? Any other suggestions?
2) around what price should I list my old flute?
3) Are the flutes I listed even much of a step up? I know Gemeinhardt's have a bad name now, but this is an older model.
4) Any bartering suggestions? Or just a bad idea?
5) What are your favorite flute sites to test flutes on a trial basis?
Thanks, and I'm looking forward to joining this community!
