i always find that riggers have to max their nuyen allowance like deckers.
riggers are entirely about gear and can survive on pretty basic attribs.
You've got some pretty expensive cyber, so if you're allowed to take used, thats a good way to free up cash.
second hand vehicles can free up cash if they're allowed.
the other thing to remember is that logic isnt amazingly helpful to you if you're not doing much with it (first aid and mechanics etc) it might be cheaper to just dump the cerebral boosters and get a manservant drone with pilot 4 and profession 4 autosoft for your repairs.
The other thing to consider is that large drones are like mobile tanks. you're not realistically going to be able to use them on all but the heaviest of assaults.
maybe a small fleet of rotodrones would be more useful investment?
you can pack down a roto-drone or doberman into a backpack or store it in the boot (trunk) of your car.
sticking an AR with underslung grenade launcher each on a couple of rotodrones is more concealable and brings multiple threats to a fight. they dont need to drive in through a big doorway/garage and be carried in a large van and can serve multiple roles (ie one can scout ahead while the other covers your escape route)
as for AGI, if you're planning on walking in with your team and using that shotgun you'll need a better AGI, if you're sitting in the van while they do all the heavy lifting, you'll be fine.
the cost for 2 ranks of muscle toner is pretty negligible but the benefit is huge.
