Thank you all so much for the replies! I really appreciate them. I've taken everything you guys have said and tried to put together another list adding in all the components I liked from your lists. Here it is:
Lord Commissar w/ Powerfist
Company Command Squad w/ Astropath, Chimera, 2x Melta
Straken
HQ - 335
Marbo - 65
Elite- 65
Al'Rahem - 70
Company Command Squad w/ 4x flamers
Infantry Squad
Infantry Squad
Infantry Squad
Infantry Squad
Special Weapon Squad w/ 3x Meltas
Veteran Squad w/ 3x Meltas in Chimera
Troops - 490
Scout Sentinel w/ Autocannon
Scout Sentinel w/ Autocannon
Scout Sentinel w/ Autocannon
Fast Attack - 120
Leman Russ Battle Tank
Heavy Support - 150
Ok, so my idea here is to make a platoon with my Company command, platoon command and infantry squads. Straken gives them some punch, and Al'rahem gives me my positioning on the table.
Marbo pops on where I have a sticky situation to take care of and hopefully blows them up.
The company command gives up their chimera for the special weapons squad to jump in. They then tag along with the veteran squad to go hunting.
Scout Sentinels outflank onto the table where needed, and hopefully pop whatever they can while giving me extra units on the table.
Leman russ does its thing and blows everyone up
This list satisfies my need for some vehicles, a blob and some killing power. It also helps my budget

I can build this list by only having to purchase 3 battleforces, 2 chimeras and a leman russ. I may have added 2 hydras instead of the russ if there was a model available, but deep down I love the russ.
