Let me start by saying that I'm 100% certain the Meizler module will be awesome, and worth every penny.
Although I want all the functionality of the Meizler, I only use my rig for personal projects, so having one integrated unit with big-brand focus compatibility isn't as critical to me as cost. Here's my stab at assembling equivalent functionality out of cheaper/less-integrated components:
Video: Paralinx Arrow - $1200 (inc Tx and Rx)
Audio: Lectrosonics SR - $2300 (inc mounting hardware and cables)
Focus: RedRock microRemote - $2600 (inc Tx and Rx) or RTMotion Basic Package - $2600 (inc Tx and Rx)
Battery: VF or WC V-mount solution w/ DTAP - $600
Total cost: $6700
Advantages over Meizler: about half the cost, includes Rx for video and Tx for focus, production-quality stereo audio
Disadvantages from Meizler: not an integrated module, no wireless time-code
I'll post some shots and thoughts once the final pieces arrive... definitely won't be as elegant as a proper Meizler, but I will be excited to de-tether focus and sound from the camera!
