Lucky for me I got divorced BEFORE I got into brewing...so when the next SWMBO comes along I will have thing by and large bought and paid for.
Having said that, I dropped $500 last week- got a keggle, fittings, tubing, ball valves, and connectors...it goes QUICK. I still have about another $400 to spend (Temp controller, pump, MORE fittings, grain mill) before I am where I want to be at with my brewery. The good news is that I am nearly done after nearly a month of planning, welding, drilling, redesigning, welding some more, planning, ordering, waiting, bending, redesigning again, welding again, and putting things together.
Fun fun fun hobby.
