DaremoS .... i haven't got it yet, i'm waiting for it. i ordered it.
i've read some czech reviews of T39 and e.g. (dont know how to say that in english :D) content of package is much poor that content of Emgeton's package (e.g. earphones - Teclast's are little shits). And Emgeton's support is much better than Teclast's (in Czech rep., don't know how it's in other countries).
Result - Emgeton WINS 
P.S. - i have two older Emgeton players - X6 and E3 and i'm absolutely satisfied with it.
