Just got a great deal on a SparX Helios modular for $50 on eBay http://www.ebay.com/itm/111047295315?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649. (http://www.ebay.com/itm/111047295315?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649.) I love my SparX S-07 I got a few years ago, fits like a glove. But the Valley is just too hot for a full face in traffic in the summer, so I chose the modular over open face.
In my searching I found this great deal on a SparX S-07 Corsa. Great looking in Duc colors.: http://www.ebay.com/itm/160917860881?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649 (http://www.ebay.com/itm/160917860881?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649)
If you haven't tried a SparX helmet, they are worth a look. Really high quality even for their normal price of $130+. But on close out, you can get a great deal.
