i have the gp3, the vestax, the numark, the big bird and about 7-8 other random portables, and i find that i mainly use the numark for doing the markets, thrift/junk stores, but avoid using it at larger record shows where i find it isnt loud enough (even though i only ever use it with bose headphones) so i use the vestax which i have personally found to be a little louder. i think the gp3 is probably a better all rounder, but i only have a ltd clear gp3 and seeing as how much the others get beaten up i dont like to take it out.
