Ok, after considering your request for a 1,000 point list and the previously mentioned "good buy" using the Strike Force, I've come up with the following as an example of something to build. After examining the box contents and checking the Codex, I'm going to recommend the following.
HQ 335
Captain w/ Power Fist and Lightning Claw
Command Squad w/ Champion, Apothecary, and Razorback w/ Las Cannons
Troops 404
Tactical Squad w/ Plasmagun and Sgt w/Combi Plasma
Tactical Squad w/ Plasmagun and Sgt w/Combi Plasma
Scouts w/ 4 Sniper Rifles and Missile Launcher
Elite 146
Dreadnought with Plasma Cannon and Drop Pod
Fast 115
Assault Squad w/ Plasma Pistol & Power Axe on Sgt
This is able to be built with all the kits included in the Strike Force and does not require bitz from any other kits.
I realize the Captain has two Close Combat weapons, but, that's intentional as both are Specialists Weapons and can let him strike at a couple of different initiatives (depending on the situation) and two different profiles too.
The Command Squad is there to support the Captain. The Champion is a beatstick and can accept challenges you want to keep the Captain out of. The Apothecary gives your unit (and the Captain) Feel No Pain. The Razorback is best equipped with the Twin Linked Lascannons as the Heavy Bolter is not that useful by comparison.
The Scouts will deploy at the start of the games you play, pick a good spot for them and unleash their potential.
The Tactical Squads are your gun lines and the plasma weapons in them have the same 24"range as the Bolters, plus they also have rapid fire. This prevents you from having a weapon with an odd range forcing you to get close for things like Melta or Flamers. The Combi Plasma on the Sergeant can Rapid Fire too, FYI.
The Dreadnought is going to play havoc with your opponent and should be difficult to deal with, barring their die rolls. Don't forget to shoot the Stormbolter on the Drop Pod, its not a big thing, bit can help.
The Assault Squad will throw some static in the opponent's line. However, I would have them support the Captain and Command Squad.
Hope that helps.
Someone toss in some C&C.
