Budget Chinese Tube amps - any good?

In the midst of searching for a budget tube amp. Lots of chinese made models keep popping up. The price on these amps are often really low and would give someone like me a chance to try the tube sound for cheap.

Do you guys have any good experiences with them?

Reason I'm asking is that I hear many conflicting experiences online on each amp. Some say their amps are really good, some say they are really bad - each model might have 5 good reviews and 5 bad reviews. I guess this is par for course with audio, where subjectivity is the rule of the game. However, chinese amps tend to have the largest disparity of opinions.

The models I've read up on so far are: Mingda amps, Miniwatt N3, Yaqin amps etc.
