Everyone else has said great advice. If you are interested, here is a list of all the tools we bought over the last season:

Also, I see your location is San Francisco. I'd be happy to talk with you and your team in person about shops and tooling, whether we come to you and check out your space or you come down to our shop and see our setup. Feel free to send a PM and I'm happy to arrange something.
