I would say if want the touch screen player get the proper Onda vx747, but if you do want something cheaper then go for
this non touch screen, it's good value for the 8GB one, It's quite a solid player, the battery life seems quite good and it IS the full 3" widescreen.
If you look at the PCB photo above bottom right over the earphone socket, there was some masking tape over the earphone socket to prevent shorting out, I moved it a bit and now I have no problems, not even the buzzing sound I got before.
Only thing you have to watch for is there was a virus in the firmware partition and if you set the backlight below 3 it goes out so you can't see to navigate, but the audio with PlayFX is very good and its very handy not having to convert movies and clips. These things are improving all the time so it's not always worth spending too much money.
I seem to buy a new player every 9 months or so anyway, I've got 4 cheap ones now, and they are all still working.
I will try and do some tests on the battery life and feedback, but the battery is big and
the player quite heavy.
