Personally, I don't believe in 'starter' helmets.
The bottom line is if you go about things this way, you're going to end up spending twice as much in the long run. Trust me, I learned the hard way. You'll buy the Rubies, then quickly tire of it, hate it, and be desperate to upgrade. You'll end up buying two helmets, mark my words.
The best thing to do is this: BE PATIENT. If you're on a budget, save your money and buy a Marrow_Sun.
You'll thank me later.
