Mantic Games has some really cool robot models scattered in their Firefight line. And I'm pretty sure the models come with some weapon options. I've had my eyes on the Asterian Marionettes for a hot minute to play with for One Page Rules.

This is true, this is true. Especially since my quar are doubling as a proxied astra militarum army I can do what I please. Vox speakers fit AMAZINGLY on Quar apparently.

I got extremely hyperfixated on it and read through a huge chunk of them in one night I fear. Almost all the beasts are only used by Royalists, and as a Crusader girly I'm bummed that it's not lore accurate to use them. (I will use them anyways if they get models)

If you go to the Rhyfler website, it has a link to a shop which carries free PDFs of the rules and lore (I'd recommend starting with Western Iron). Even if you don't want to read a history lesson, the art in them is fantastic and so so silly.

It reminds me of the Quar mounts in the books, which I DESPERATELY need models of.
