Looks like starter forces are about 25 guys (100pts) for $65. Ships are a bit expensive but look great (add about $60-100 to a starter force). The ships also come with tons of stuff(The Light frigate comes with 15 Wooden dowel for Masts & Spars 4 Yards of Elastic for Rigging 6 Light Cannons on Carriages 8 Cannon Barrels 4 Swivel Guns 22 Rigging Parts 14 Gunport Covers) No sails included though but wouldn't be hard to make them.

Most forces have essentially two different army lists within each faction.
