Pick one up for $1-1.2 K with a hand controller.

Install is plug and play (+ swapping the cam & crank sensor inputs on non-sti wrx's).

Drive on base map to All Star for a tune ($4-600 depending on time it's on the dyno)

Budget for around $1800 all up.

Secondhand PFC's can be had for under $800 if you're prepared to look / Wait.
