Buy everything used. Starve the beast.
I like it when new stuff comes out. Then I pick up the old stuff for cheap. That's how I got my Mac Mini Server. The seller upgraded to a new one, and I bought his old one for half of what a new one costs, it had been upgraded with max ram. And got it loaded with $1700 worth of software. All I did was swap in a solid state drive and it is fast. A lot of bargains out there folks, when others buy new and unload their old stuff. Who cares if it's a couple years old, they last a long time.
