I've had luck with Cyco Pearl - coir with perlite already blended in.
It's available locally so an easy choice. No shipping charges etc.
It is prebuffered but the runoff is quite strong. I've been running a bit of a flush with seedling strength (300ppm) nutrients until the runoff numbers drop. pH stays pretty stable.
