I'm not familiar with this disc, so I can't comment on how " good" it is.
However, I feel the $35 - $40 for Avia is VERY MUCH worth it since you get "trusted" reference test patterns and tones as well as the disc being popular, so it will be easy to get help using it.
You could try with the disc on eBay, but I recommend buying Avia.
Peace.....
