hi folks i am thinking for going in for a 2nd hand ibz 370.it's only 3 months old edgeIII model.he is asking for 15K.have not seen it though.what do u guys think? how stable is the edge III as far as tuning is concerned? does the wizard II neck warp easily,compared to say ........a kramer? would you consider it as a step-up from a kramer striker? or do u think i should go in for a custom from albertos?
