hi, I damaged my last one by knocking one of the buttons an now it's consantly changing channels etc..doing my head in now, tried messing with the button but no joy..it's one of these eonon things and to be fair worked well until I messed it up, so I'm looking for another similar thing..seen loads on ebay from china but unsure if it's worth the risk..don't want to spend a lot in fact under £100 so think I'm gonna be stuck unless I find one used on ebay..

any thoughts lads?

many thanks in advance
