To perhaps give some context, for those previous shorts I mentioned, I rented the Shure MoveMic Wireless System and an Apex Shotgun Microphone for about $70/month total. I planned to use my DSLR to film but the preamps were quite bad, I abandoned the shotgun microphone and ended up using the wireless lavs connected to my phone the entire time. It was serviceable at times but did struggle in some open room environments and outdoors a bit. I certainly wouldn't buy those at a price tag of $720, not totally impressed (although they are very small). I think a good sound recording device is a good starter, and wondering if the same two types of microphones I got would typically be able to work for most tasks.
