When a piano string is struck, the sound is relatively consistent each time. The rate of decay (called envelope) is consistent. So sampling can create a good result. With a reed instrument, there are many more ways that the sound varies with breath, embouchure, attack, tongue, interval jumps, and much more. I think that's why the wind synth is missing many expressive qualities.

BUT there is hope - a friend of mine has a Roland EWI. I think its reed and flute sounds are terrible, but the violin sound is excellent and beautiful. That's a complex one, so I am surprised. We will see more improvements, for sure.

I was disappointed by both digital instruments I tried. Of the two, I think I would choose to have the Yamaha digital saxophone back again for some voices. But the problem is that the voices sound fake-y to my family, who are used to hearing me play real instruments.

With today's high quality piano samples, one would think that sax and clarinet sounds have improved.
 I assume the breath controllers are up to the task but maybe the onboard processing can't cut it!

If this is the one you're mentioning,

This was my listing from several years ago. Surprised it still shows up on Reverb.

I would definitely go for a Yamaha vice Chinese Jean Paul.

However, there is a Chinese maker, Kenny Woodwinds, who makes an incredible clarinet for around your budget. I don't know if he's still in business, but last I checked they were selling for around $300, and were poly-cylindrical, nearly pro-grade for a great price.

Chinese instruments can be good but they are prone to small defects from semi-skilled assembly and lack of player-testing. The Yamaha, if overhauled by a good stateside professional, is a fine-sounding instrument, well made, and more likely to please.
