The other reservation I have is how long a wooden instrument would stay better. The plastic instrument is going to be exactly the same in 10 years' time, given the occasional dose of warm soapy water, but the worst instrument I've ever heard was a Moeck Rottenburgh - probably because if the inside of it was as filthy as the outside, it's amazing it could make a note at all.
Wood's definitely harder on the maintenance, and if an instrument's windway is full of congealed gunk and fungus, it's not going to make a nice sound (as well as being a health hazard). So although part of me is very tempted by a good starter wooden instrument like the cheaper end of the Rottenburgh range, another part of me thinks that I'd be buying it 5 years too soon, and by the time I'm ready to benefit from it, it will have decayed to the point where it can't yield the benefits.
OK, I could get the wooden recorder and get it serviced properly from time to time, but I know I won't find the time and cash to do so... and I'll get frightened of messing it up, so it will live in a box and never get played, while I carry on using my ancient aulos.
Human psychology is so frustrating.
