About how much $$$ would it take to restore Toor to his full potential?

Maybe I am more of a newb than I thought but I have no idea what Toor is. Did a google search for star wars Toor and came up empty. Could you give more information please?

In the Age of Rebellion beginners game he's a commando battle droid that was salvaged in a junk yard and was refurbished to do janitorial duty. I was guessing about 30,000ish credits because that close to half the cost for an assassin droid, but I'd like some input.

I'd say that depends on how tough you'd want him to be when he's fully restored. Look at the stats for assassin and security droids in the rulebook; if he'll be that badass, set the price accordingly. And don't forget, someone has to make all those Hard and Daunting Mechanics checks...

If my understanding of Toor is correct, he is only a standard battle droid as of Phantom Menace. As such he is only a minion droid so I would say not much work is needed. Largely repairing any damage to his armour (what little he may have) and giving him a blaster. Obviously this is once the restraining bolt is removed.

I've read the part of the beginners game adventure about Toor, and appartently he was "...rebuilt and refitted for the demeaning task of cleaning the base." What I get from this is that most of his limbs were replaced and he has little of his armor left. His programming is still intack though, (and probably messed with to make him less agressive) so if rebuilt, my PCs (also known as my family) will have a droid companion! "That'll be 35,000 credits."

Toor is BX-series commando droid. This was an elite series of powerful Clone Wars-era battle droids:

If you look at his statistics, he's actually quite powerful already.

In the EotE rulebook, the "Security Droid" costs 9,600 credits and is comparable to (and, overall, probably somewhat weaker than) Toor's current status. Upgraded and repaired, Toor would become even more powerful.

So if you're going to allow the PCs to basically own Toor and use him for their own purposes, getting him in full working order should probably costs them no less than 10,000 credits, and maybe more like 15,000+ depending on how much you permit him to be upgraded.

Personally, I'd forget the credits and make it an adventure. Run a pan galactic treasure hunt / goose chase looking for old CIS supply bases, bunkers, comms stations, and convert strike bases trying to get parts and untampered programming needed to get Toor back to 100%. Have him know (or claim to know) the location of a lost trade fed reserve fleet worth significant credits credits in salvage. Of course an imperial security team already has a head start....

I was planning on running the Perlemian Haul adventure after they successfully defend Whisper Base, and I planned on having battle droids of some kind on broard freighter M226, (for the sabotage duty) but there could also be info that leads to an adventure as you recommended. Thank you very much for the idea!
