I am about to purchase a Sony DSR-PD170 from B&H to shoot weddings. One of their offers comes with a Sony UWP-C1 mic. But, one of the sales people recomended the Sennheiser Evolution G2 100. I would save $100 if I go with the Sony UWP-C1. I know it's not much but, every little bit counts. At the same time if it's worth it I'll pay the extra hundred. Can anyone help with which mic is better or is there any equally good mick for less. Thanks.
