PREACHPersonally I find a decent starter kit like Kengertech subox Mini is kind to the wallet and comes with 2xOCC and 1xRBA. Easy to use and small enough to keep away from attention. Did I mention it also includes one ready made coil and some cotton for the rba as well? So technically you can use this kit for some time if getting your hands on the replacement OCC and wire/cotton is challenging in this country.
