Wheels + Spacers question

im in the market for some rims but i only can afford used one at the moment and thier some great deals to be had here in the market fourm. now my car has bbk setup and most of the wheels will not clear them without a spacer. so i was wondering wat difference would it make if i bought a rim with high disk front to clear brake Vs normal / low disk front and adding spacers to clear brakes? would the rims look / fit better with the high disk front vs adding spacers to clear the bbk?
 
 
thanks
