Hi Mitch,
Mine was only around $80 (reduced from $120).
To be honest, for around that much you really cant go wrong. As I bought it from a large motorbike store, they had around 5 or 6 different models in a price bracket ranging from $70 to around $150 if I recall correctly.
So yeah, basically I tried all of them on and went with the one that gave me the best fit (and it just so happened to be very reasonably priced )
All in all, I think its money very well spent. Go to a handful of track days and its paid for itself anyway considering you'd be looking at $20 or so to hire one.
And this way you have one that you already know fits well, that you know the history of (ie it hasnt been dropped or abused by other people who've hired it), and you don't need to worry about finding one to borrow each time you go.
Hope that helps mate
