drive help

[normanji]

hi all got a ps3 here bought for £10 bit fucked the guy i bought it off got a game stuck in side he managed to open the console and get disc out, i've had to reset the drive mechanism but the drive now will not take any disc. i've had it open and the drive fully open while switched on it plays all discs but wont eject or take any disc i removed the motor that operates the eject mechanism and it does not spin when the eject button is pressed, does any one know where i can get one of these from

thanks in advance

just to let you know its an 80gig version if that helps i've just took a 40 gig apart to try the motor in there but its got a different circiut broad on the motor so it doesn't fit.
