Some of the highest things on my list would be as follows.

Non-ferrous cutting blade for your chop saw and a good clamping and work stop rig

I would look at buying used machines, California has a lot of quality used machines around especially in the Bay Area. I would love the chance to talk with you in depth about your many options for machines and tools. Send me a PM if you are interested. The same goes for anyone else reading this thread, I'm always game for talking shop and sharing how we run ours.
