Syndicate Robot Frames.

[BaneOfGiygas]

Syndieborgs are better than mindslaves, plus cheaper too.

Well, that depends on your definition of "better", really. Mindslaves may have a time limit and cost an extra TC, but they have one thing that puts them above cyborgs in usefulness: The ability to pick things up. Syndieborgs, while they may be permanently loyal, have a wide arsenal, slightly less conspicuous as most people will just assume that someone's messed with the AI, and be sturdy as hell assuming you've reinforced them like a smart roboticist, have a few noteworthy caveats: They tend to be rather slow, they have very little flexibility, and their direct combat capabilities are rather limited as a result of their predetermined inventory. The closest thing a Syndieborg has to a straight-up "weapon" is the likes of a fire extinguisher or scalpel. While these are fine combat tools, they don't compare to the kinds of things a mindslave could get their hands on if you send them over to sec or lend them some of your gear.
