I am constantly asked where I rent equipment or what rental houses I recommend. So here is a list of some of the ones I trust and use regularly:
My first stop for most rentals. I have been renting from LensRentals (easily 200+ orders) over the last 10 years and they have been a joy to work with. In all of my orders I've only received one damaged item (probably happened during shipping) and they fixed it promptly with an overnight replacement. Their staff is friendly and knowledgable, and they have a wide selection of gear to choose from.

When you're looking to purchase gear but can't get a demo, renting before you buy is another option (and something I constantly recommend). Adorama is one of the leading sellers of photo and video gear in the United States, and they offer a wide selection of rental equipment along with a "Rent Before You Buy" program. If you purchase a product through Adorama within 30 days of renting that same product, they will refund 100% of your rental (up to one week's rental fees).

PRG Gear (formerly VER)
One of the largest gear rental companies in the U.S. (and many locations across the globe), PRG Gear has a vast selection of quality equipment. Most large shows and projects I've worked on have had truckloads of PRG Gear rentals.
