I tried these (sorted my least favorite to my favorite):
Yamaha YFL-361
Azumi AZ2
Sonare PS-501 (and 601!)
DiZhao DZ600 - I actually loved my sound on this one and the Sonare the best, but the mechanism didn't feel as solid.
Pearl 665 (winner!)
And for fun I tried an Altus 907. Which was by far my favorite, but out of my budget, especially as a divorced single mom out of practice intermediate hobbyist!

Onto a couple of questions:
8notes.com - is the subscription worth it? I like the idea of it, I do everything online now, makes sense to find music and play along online also. Any other practice websites, etc. that you suggest? I've been using google's metronome to practice my scales.
My middle octave Eb on this flute just does NOT sound right. I am using the correct fingering with my left pointer finger up for venting, and my middle D sounds pretty darn good (to my ear). I'll admit that while my tone in general needs work from being somewhat rusty, it sounds too bad to be all my doing. Did a little research and sounds like it could be a venting issue, or that the Eb pinky tone hole isn't opening enough, or a combination of the two... I know I can bring it back to where I bought it, but to be honest, I'm not sure if I want to let the band instrument technicians there have a go at it. Not that it's a $10,000 flute, and I guess I should at least let them know I think there's something amiss. It was his last one in stock, but I'm sure he is planning to get another anyway and I can test on it and see if it replicates. Any advice? Is it worth shipping it out even though it's brand new, to a flute specialist technician for a lookover/tune up? How much does something like that run?
Thanks!
