This threads been around for awhile, but I'll add on. First off, the polymers (PVC and Delrin) used for flute making are not the same grade stuff that is quoted above as harmful to kids. Check many modern homes plumbing systems, and you're drinking from PVC pipes. Also, many PVCs are food grades.

As for good polymer flutes, I've owned both a Tony Dixon 3 piece conical flute and now I have a Desi Seery polymer pratten style flute (I like the big sound baby!). Both compared favorably with blackwood flutes I've either played or played with in sessions.

I bought a nice antique flute I had been playing for a few months, and although I love the keys, I've switched back to the keyless Seery because it's such a fine flute.
