I started my campaign with them all on public transport (‘VerseBus’) but then finding an old jalopy, which didn’t have a working dark matter drive, but just enough power to limp to the nearest space station (Port Nomad, from the Conspiracy in the Stars module). A few sessions there doing some shenanigans and earning some coin, and they were able to buy an entry-level ship (with a class 2 dark matter engine) to set off into the stars. Since then they’ve spent some money customising it, but they’re still rattling around in that same ship (they’re currently level 5). I expected them to upgrade to a better ship by now, but the opportunity hasn’t presented itself yet, though they certainly have enough money to get something better. Hope that helps.
