Here is my 1500 mech Pedro list I expect to be using this weekend.
10 Man Tac with Powerfist, Meltagun, Multimelta in Rhino
8 Man Sniper Scout Squad with Cloaks, and Missile Launcher
10 Man Sternguard Squad with Meltagun, Combimelta, Combiplasma in Rhino
9 Man Vanguard Squad with Relic Blade, Powerfist, Lightening Claw, Power Weapon, Meltabomb in Rhino(Pedro goes here)
Landspeeder with Multimelta and Heavy Flamer
Vindicator with Siege Shield
Predator with TL Lascannon, Heavy Bolters
I pretty much dropped a landspeeder and a dreadnought from the 1750 list. If I did a 1750 list again I might try to get a 4th Rhino with some of my new honor guard.
