Well, I always went with Vistek in Toronto...until I had a bad experience. Rented a lens for the DVX100A...and got it to the shoot only to find the lens was totally scratched all to heck. Too late to go back. Had to complete the shoot without the lens. When I returned it to Vistek the next day, they were extremely rude and dismissive. I explained that I lost my shot because of the scratched lens. They just said, "So. What do you want us to do about it?" I was like, "Well maybe apologize?" I guess no matter who you rent from, you better check the equipment right there at the rental place BEFORE you leave. Because they don't care if you get your shot or not.
You looked into LIFT or Charles Street Video? They're very honorable places. Focus is more on film for indie filmmakers, but they may have video equipment too.
