Best place would be Subaru themselves. I usually find the dealer surprisingly fair with their prices. I'm sure other places can source genuine parts as well, but they all come from Subaru originally. And by the time that company puts their markup onto it, you might find it's not any cheaper (even if they do get a trade discount).
I don't think the rubber boot itself should cost much. What cost a lot was getting the whole CV shaft/joint replaced (like in my case). That was mid $300 for the part. But the rubber boot itself should be pretty inexpensive.
With really expensive parts, it's worth sourcing from overseas (Subaru in the US, or JapanParts). They are cheaper, but the postage can be a killer though. So with my $900 centre diff it was worth it, but paying $20-$30+ postage on a rubber boot that may be less than $75 (maybe even under $50), it's not. And you don't want to be waiting 2 weeks, since you could do damage to the CV joint driving around with little lubrication in the meantime.
