I'm starting up a Space Wolves force, and this is the basic 1500 point core I am thinking of buying (off of which I will expand). I will primarily be playing non-tourney games against 'Nids, Orks, Guard, and Black Templars.
Rune Priest - 115 Chooser of the Slain; Living Lightning, 5+ Ward Power (can't remember the name)
10 Grey Hunters - 210 Flamer, Melta, Powerfist; Rhino/Drop Pod
10 Grey Hunters - 210 Flamer, Melta, Powerfist; Rhino/Drop Pod
10 Grey Hunters - 175 Flamer, Melta, Powerfist
10 Grey Hunters - 175 Flamer, Melta, Powerfist
Dreadnought - 150 Multi-melta, Heavy Flamer; Drop Pod
Dreadnought - 150 Assault Cannon, Heavy Flamer; Drop Pod
Vindicator - 115
5 Long Fangs - 115 4 Missile Launchers
Whirlwind - 85
Total - 1500
I am currently planning to also get a basic Predator with autocannon turret and side heavy bolters that could swap out for the Whirlwind.
