The FG-17 actually retails anywhere from $250-299 depending on the year/design. I'm looking into purchasing a large lot of them for my work and selling them Snell rated for sub $200. But yes, they are a good helmet, Both N3WMAN and I wear them and I have seen quite a few others around the track. Best fitting and feeling helmet I've ever had.
I also have a FG-17. Best fitting helmet for my head shape I've come across, regardless of price.
I just wish they made 25mm cheek pads. I'm between the 30mm and 20mm.
