He's just starting up, but has an okay selection of Canon gear (better than Lens Lenders, that's for sure), and at reasonable prices. Saved my butt when my 50mm f/1.4 broke. The Nikon stuff is supposed the be in later this year.
Lens Lenders is just way too expensive. Stay away.
Headshots Rentals based out of Toronto will ship your rental to any Henry's store, and you don't pay for the rental while it's in transit, obviously. I rented from the location that they used to have here in Ottawa and it was great.
Recently, I've been renting from Vistek, because it's easiest just to reserve it a couple of days ahead of time, instead of a week or more that would be necessary for ones that come in the mail/courier.
