Cheaper, but still quality mics, I’d go with anything made by Shure.
You can even get some mics bundled into a “drum kit mic package” for a little bit less than buying them individually. Get something with some Beta 98’s that can clip on either Toms on a drum kit, or be used on your conga. For the cajon, I’d probably throw a 57 on the front and a Beta 52 on the back. The 57 can double as a snare mic and 52 as a kick mic.
