looking for boost control

i have one of those little screw type deals but its pain in the ass.
i want to buy an electronic one like the greddy profec or the apexi or something. so i can set boost and have like high/low setting all from inside the car, but dont want to spend crazy money. does anyone have one that they want to sell, or know where i can get one cheap.
from people who have one, is it worth getting or should i just keep the crap.
thanx

Get a turbo XS Dual Stage Boost controller

you can find them new for like 200-250, they have 2 settings with an In-car switch, i dont have one but i will eventually
