Cheap helmets are to protect cheap contents. (if you have a $25 head buy a $25 helmet)
I would look for a current Snell Certification first, then the quality of materials used, then the fit, finish and lastly any options and paint scheme.
When I was a bike guy, I had done a lot of research on helmets and my top 4 Snell M rated helmets in order of price for good quality and features.
Aria , Shoei , Bell, HJC I have used all 4 brands and feel you would be well protected with a top model from any of these 4 manufacturers.
