What's your favorite rental house?
 

I'd like to get your rundown on favorite rental houses. Specifically, I'm looking to rent a shoulder mount and viewfinder for my 7D, of some sort. I'm shooting a wedding for a friend, for free. I've only shot shorts before, never a live event (I've only used traditional tripods), so the shoulder mount will be new for me. I'm way open to ideas and suggestions. The lowest price doesn't necessarily win, but seeing as this is an unpaid gig, the best value will win out.

Thanks for reading/replying!
