Advice Please....!

HELP!!! I need new running trainers and went to a specialist running shop this morning who informed me after inspecting my feet and gait etc that I need a neutral trainer! I'm not really sure what this means I run like but can anyone suggest a good shoe? Asics V's Saucony? Is it worth spending silly money or do you get similar with cheaper trainers? I'm sure some of you with years of experience can advise me...!
