In terms of mics, the EW100 series seems to be standard issue: The cheapest radio mic worth getting. We also use a range of directional mics and for studio recording, such as

• directional mics, such as ME66, ME67, though some people advocate getting more modern designs (that transmit less noise)
• Sony ECM-77 for wired tie-clips.
• ME62 for general recording, though haven't tested this much.
• Low cost Behringer M58 for hand-held interview work (there's also an audio technica equivalent)
• Range of studio mics for professional studio-based voice recording.

We use the EW100 G2 series, which runs perfectly on high capacity AA rechargeables. The pre-G2 models (with PP3 blocks) never ran well on rechargeables, and the G2 series was an amazing step forward in that respect.
