Two of my kids are goalies. So in other words, I am crazy! Both have been goalies for years, so I have lots of experience in buying and selling goalie equipment. Plus I was an equipment manager for a local hockey association.
My suggestion is to go to Don Simmons Sports in Fort Erie. They deal only in goalie equipment. That is all they do.
They have their own brand and trust me, it is good quality for a fraction of the name brand equipment. It is Canadian made, most of it is made by a company outside of Orangeville Ontario.
If your son needs a mask, please make sure it fits correctly. have someone who has some knowledge make sure it is adjusted correctly. It depends what level he is playing at. If he is playing in a house league under Bantam age, the decal style ITECH masks are fairly good. If he plays rep or higher, and or is Bantam or above, you may want to buy a more SOLID mask.
Plus there is a new huge hockey store in the Vaughn Mills Mall. It is down by the Nascar store. People there should be able to make sure the mask fits correctly.
My suggestion still is
