Converter Comparison

This is my first post here so please bear with me. At our church we have 2 cameras that we are running HDMI out of into blackmagic hdmi to sdi 6g converters. We purchased those from bhphotoandvideo. They say they are now discontinued. What can we use for a third camera? I see cheaper options from blackmagic like the micro converter. Will this be the same thing basically?

They got replaced with a revision of the model. Which got cheaper also.. Here the link to the new unit

You can use the Micro converters too if you dont need to embed audio, do LUT processing inside the converter or have any processing going on..
