In reply to JohnV:
While not having a flat top and slightly above your price range, my Julbo Orbiters fit nicely with my Sweet Igniter and just about any other helmet. They are also by far the nicest goggles I have ever owned. The photochromic lenses are awesome and negate the need for a second lens, and about the only thing more durable (ie the only other goggles i've not broken within a season or 2) is a good old pair of A-frames. Worth the extra money imo and still cheaper thank Oakleys.
