Blood Angels: an Army that Grows -- 750 --> 1000 --> 1500

The list begins at 750 points:
Dante
Sanguinary Guard with infernus pistol
Devastator Squad with 4 missile launchers
Assault Squad with 8 marines and thunder hammer

The list is added to to make 1000 points:
Tactical Squad with missile launcher, power fist, flamer and rhino

The list is added to again to make 1500 points:
Furoso Dreadnought with blood talons and drop pod
Sanguinary Guard with infernus pistol
Devastator Squad with 4 missile launchers

Given models already owned, this is the cheapest list to develop up to the 1000 point mark. I only need to buy: Dante, Sanguinary Guard, Devastator and Army boxes to achieve this.

I'm missing the Sanguinary Priest in this set-up; also the chapter banner I'm not sure how important that is, or if the priest and/or banner are worth the points anyway.

This will be my fun list/army.
