I'm planning on build a cooler-based jockey box to drink my kegged beers. And was thinking what's the different things in a beer tap/faucet? I'm having trouble to find one with reasonable price in my town.

I understand that some faucets have 'cream function', or 'flow control' diferences, material finishes (stainless, chrome plated, brass, plastic..) but the standard/basic type just allow you to on/off your flow of beer. Rigth?

Can I simple choose other kind of tap to put on my draft box? That's just a matter of style or its needed by some reason?
