nah, i'd quite like one for charity shop digging though. I just get things i know are decent, or i'll take a punt on a £1 album, or maybe a 50p 7". Any knowledge i have(which isn't a great deal)has come from trial and error - i've bought a lot of crap over the years. Still buy some crap, just a lot less than i used to. same for me, really. except I actually have numark pt. Ive never gotten round to using it while digging though
