Yeah it all depends what route you go. Mine was this: replica ltz housings ($375), RX-350 BiXenons ($200), Mitsubishi Gen IV Ballasts ($200), and Philips 85122+ D2S bulbs, ($100). That however gave me a fantastic setup and no real need to touch the high beams due to BiXenons nice high beam performance. Wouldn't look back in my case I love it.
