After a look at the robot industry I'm now a fan of MK2 Protectaponies. Not as powerful as Mr Macintosh, but cheap to upgrade (save for the AI gem, which can be copied at the Talisman Forge) and don't have a flamethrower.
I'd also like there to be a third type of turret upgrade. Here is my rationale:
* Flamethrower turrets tend to set the map on fire, no longer have their basic small calibre bullet attack and I hardly ever saw them doing much to enemies.
* Miniguns and medium ammo crates are very expensive, scarce and useful for a lot of things. After thinking about it, I've decided to reserve at least the first five for battle saddles. Then there is reverse-engineering, other types of robots, as well as limited steel and potash production speeds to put my minigun turret production on hold until well after I get bored or FPS becomes unplayable.
* Basic turrets are pretty weak. They don't do much to enemies and are quite easy to damage.
I'd like some turret upgrade that gives it steel plating and maybe an extra attack or more damage. Less effective than minigun, but actually affordable to mass produce / upgrade. I have these ideas so far:
* Just put more armour on it and generally refubrish it. Uses up steel plating and maybe scrap parts and wiring. Gives it steel armour and slightly increases attack speed. (For example by lowering wait period on shooting bullet to 25.)
* Rifle turret. Needs steel plating, 2 combat rifles and at most 1 crate of medium calibre bullets. Preferably just 4 stacks of them. Shoots medium calibre bullets, but not nearly as fast as the minigun version.
* Energy turret. Uses steel plating, battery, wiring and a plasma caster. Shoots plasma bolts.

For me that would be even worse than flamethrower turrets. I want my turrets to kill enemies, not random ponies who just happened to be in the danger zone.
> Just out of curiosity, would it be possible for the craftshop to make items from paper, or would you need a new building for such things?
Craftpony's workshop makes socks, so it is possible to add custom reactions to it. This includes using paper as reagent, but to me the natural place for all paper-related things is the scriptorium.
> Just because you don't like killing your ponies doesn't mean that no one else does.
There are easier ways to do that for people who want to. Burrow in the atom-smasher, closing door to a room so the pony will starve or sending that pony to patrol map edges with no armour or equipment are just a few. Heck, if you want turrets to kill ponies, flamers might do the trick. We don't need special turrets for this.
