Just a quick post in keeping with the EPIC Eldar Tactica starting, showing off some of the models I use as Eldar Wraithships. I use some old plastic models produced by GW for their game, Spacefleet, whose models turn up with some regularity on eBay, along with the Imperial models also produced for it.
I use four in my 1000pt Craftworld Eldar fleet as wraithships, two with torpedoes and phantom lances, and two with launch bays and weapons batteries. With the addition of a GW Wraithship model as a Dragon Ship (it is significantly larger than the spacefleet models) and an autarch it makes a nicely rounded 1,000pt fleet.
As I said above the ship is a little small for a normal cruiser, but as the Wraithship is only 6DC it works quite well. As you can see in the picture it is a similar size to a GW Space Marine Strike Cruiser which is also 6DC.
Just a quick post that might save you a couple of quid the next time they come up on eBay!
