Used sets come up on eBay; most often minus the 3rd Wrench.

I must have tried to get some on eBay 8 times before I got the 3 wrench set at reaonable price and it took about 1 year to get that.

One of the tool companies on eBay is selling 1 short and 1 normal sized Hazet Valve Adjusting Wrench at about $30 less than the 3 wrench set.
