Looking at Bitshares, it seems that I need to first deposit some crypto such as bitcoin or litecoin into my bitshares wallet and then use the exchange section to find a buyer willing to trade one of these for EOS. Looks kind of like the GDAX environment that underlies Coinbase. Never used that before though so will probably try small amounts so that it doesn't matter if I screw it up. Can't seem to find a video that lays it out explicitly on how to do this, so guessing...
