So... just interesting to know:

Mine so far:
1. Stalker bolter (100% hell to the yeah)
2. Lascannon (maybe... not sure)
3. A power sword.

Heavy bolter ftw.

1. Multi-melta
2. Storm Bolter
3. Thunderhammer + Shield

Powerfist and Crozius Arcanum with a standard Bolt Pistol sidearm.

I enjoy all the long range weapons, but the power weapons are kick-a$$ too. I guess I will mostly shy away from short to medium ranged weapons.

Ranged: Plasma cannon or Plasma Gun
Melee: Power Fist. Nothing spells fun like punching a tank in the face.

Lightning Claws
Thunder Hammer + Storm Shield

Bolter with a Power Fist...
...or a Power Sword with a bolt pistol.

Dark Angel Detected! Good choice Brother ))) Don't forget we have also chainfists
Plasma For Plasma God , Skulls for the Golden Throne

Chainsword for sure... Its the most brutal, running around with a chain"saw", and cutting people in half is just a morbid way to do it.
