I prefer the Baader solar film (for telescopes and cameras) or its newer "gold/silver" version (for goggles) because it's color neutral and it shows the Sun in its true color, not some arbitrary shade of orange, green, etc.
But any ISO-compliant filter should be fine.
Do you know any welders? Are there welding supply shops near you? Welding glasses #14 are ISO-compliant for the purpose of the eclipse. Even #13 are fine for non-continuous observation.
The AAS page lists the gear that meets the ISO safety standard, along with the vendors that carry it:
