I have seen $110 quoted (by Octane Books, I think) for Ganley's book, which would tally with the £49.95 quoted on Autosport TNF Forum.
Other books recently out include Max Rutherford's "From Paddock to Podium, The Mechanic's View" - $39.95(Octane) and motorcycle champion Hugh Anderson's book at $45. I can see the Slush Fund taking a bit of a hit from these!

Also saw copies of Graeme Crosby's "Croz - Larrikin Biker" at $15 at the Warehouse.
