Agree with GM, the knockoff copies don't often enjoy the longer durability of the major brands, a lot of it depends on the user, some have better luck than others. Check out "Scale a Ton" on you tube, he has a nice bit of info about how he improves a Chinese AB, it's his mainstay for the priming and base coat parts of painting.
I use Badger, Paasche and Iwata AB's, the Badger's are my most often used. I recommend you spend some time looking at "Don's Airbrush" website, a wealth of info about all things related to airbrushes. Time very well invested.
For what it's worth, just a spray rinse doesn't really buy much relative to airbrush maintenance. Once the rinse is done, at the minimum it's best to remove the front bits for a good cleaning, then pull the needle and give it a thorough cleaning. Some thinner applied to the inside of the needle bearing with a small dental brush, will avoid having the needle get stuck as you describe.
It's best to do your cleaning with the nose of the AB pointing down, to avoid cleaner/paint getting down into the air valve chamber. Again, all of that is described in detail, at Don's website. Good luck with your search for a new airbrush, like GM I recommend Badger. My last Badger I purchased from USA AIRBRUSH, excellent service and prices.
