Having played on (and heard people play on) a pBone, I'd have to say that even though it's quite impressive to see what they've been able to do with just plastic, it's still quite some way off from being a 'quality' instrument.

And they do not prove at all that the same can be done for any kind of instrument: trumpets and trombones are a lot cheaper to make than things like bassoons - you can find very cheap brass trumpets on ebay for very little money, some of which are surprisingly acceptable; and a rather good trumpet will set you back quite a lot less than a basson only fit for a beginner.

The pTrumpet is at least as good as typical student horns I've played. I can't speak to the pBone but reviews seem positive.

Quite right, trumpets are already made in volume and thus are already sold at their marginal cost of production. Bassoons aren't. This is the reason for their high cost. I claim the manufacturing process used for pBones and pTrumpets could be used to produce a comparably-priced bassoon that would be adequate for students (it would be harder though maybe still doable with wood).
