Few questions about wireless mics

I'm a bit of a noob when it comes to audio, especially wireless setups. I am looking at getting a wireless setup for my wedding video business. From what I understand, the Sennheiser G2 and G3 are good wireless systems, but can I use more than one transmitter with each receiver? Or would I need to have one receiver per transmitter?

Do you guys know if this wireless setup is any good or do I need a much higher price range to a get quality multimic receiver?

Yes, you absolutely need a separate receiver channel for each transmitter in use as you cannot have more than one transmitter operating on a specific frequency without them interfering. If you go with the G2 or G3, you'll need two complete setups. The Shure unit you linked to would work with its two transmitters since the receiver is dual-channel but the receiver is also AC mains operated, not very practical for wedding work. The mic capsules included with it are cardioids, really intended for sound reinforcment uses and not the best for film/video where omnis are preferred.

Take a look at the Audio Technica 1800 series kit with two transmitters and a dual-channel camera-mount receiver.

You can only use one transmitter per receiver. There are sets that come with two transmitters (one lav and one for a dynamic handheld mic) and one receiver, but you can use only one of those transmitters at a time.

I've had good luck with Sennheiser G2, but unfortunately I've got a set in the 700MHZ range (lots of discussion about why this matters ... for example: http://www.dvxuser.com/V6/showthread.php?t=176790 ) so I'll be replacing soon... probably with a G3 set.
 
Two transmitters on the same frequency "fight" with each other and cause nasty noises.

The rule is: You need a separate receiver for every transmitter - but you can use an many receivers as you want with each transmitter.

The big difference between G2 and G3 is that the camera receiver on the G3 is diversity and the G2 is not.

Diversity receivers have two antennas and switch to the one with the strongest signal.

Non-diversity receivers have only one antenna.

G3 use the output cable as the second antenna for more reliable reception.
