The values of the contents are variable but it will be interesting to see how people utilise the contents!
Also on the cost ... do you have the equivalent to the content? For a marine player you would need a tac squad, rhino, assault squad and scouts. Gay Knights dip out as they dont have a battle force. There are a couple of things that will make it tricky... The Ghost Ark is also a doomsday ark.
BA = Rhino, 10 tac, 5 assault, 5 death coy
DE = Raider, 3 reavers, 10 warriors, 10 wyches
Eldar = Falcon, walker, 10 guardians, 10 avengers
Guard = ccs, 2 squads, HW squad, sentinel
Newcrons = Ark, 10 warriors, 5 immortals, 5 scarabs
Orks = Trukk, 3 bikes, 20 boys
SM = Rhino, 10 tac, 5 assault, 5 scouts
SW = POD, 20 wolves, 5 scouts
Tau = XV8, 3 XV25, 12 fire warriors, 12 kroot, devilfish
Nids = 3 Warriors, 8 stealers, 16 hormogaunts, 16 termagants
Add to this the options that are available for a single bog standard HQ and there will be some challenging games on a 4' X 4' board.
