After firing a Supa Gatler in the shooting phase, you may attempt to fire it again. On a 2+, fire another round of shots from this weapon. On a 1, the weapon is out of ammo-it cannot be fired again next round, but may be fired again after that, as the Orks inside scrounge up some debris (or grots) to fire. After firing a Supa Gatler for a second time, you may attempt to fire it a third time on a 4+. Each Supa Gatler may be fired a max of three times in any given phase.

'Ere We Go! Effigy Friendly units within 6" of this model automatically pass Morale tests.
Rigging Crews At the start of each of your turns, roll a
d6, adding one for each Rigging Crew. On a 2+, repair one wound. On a 7+, repair d3. On a 10+, repair 2d3.
Extra Melee Arms For each Mega-Choppa a Stompa is equipped with, increase its Attacks by 1.
'Eavy Spotlights If equipped with these, a Stompa may highlight an enemy unit with them at the end of your movement phase. Select a visible enemy unit. All friendly ORK INFANTRY models gain +1 to hit that target with shooting attacks. However, until the start of your next turn, enemy units gain +1 to hit the Stompa with their shooting attacks.
Kustom Force Field If one Kustom Force field is installed, the Stompa has a 5+ Invulnerable save and offers all models wholly within 3" a 5+ Invulnerable save as well. Each additional Kustom Force Field installed adds 3" to the range.
Extra Transport Space For each Extra Transport Space installed, increase the Transport Capacity of the Stompa by 10.
Wormhole Eater At the end of your movement phase, you may attempt to swallow a nearby unit with the wormhole generator inside the Stompa. Select a unit within 8", and roll 1d6 for every model in that unit within 8". For each die that exceeds the current wounds of a model in that unit, the most wounded model is immediately slain.
Transport This model can transport up to 20 ORK Models. Each MEGA ARMOUR or JUMP PACK model takes the space of two models.

without playing it extensively I'd have no idea for points I'm afraid bud. Perhaps 650, 700, all in?
