Suncoast sells new litronics for $2700. Unfortunately the days of $1200 group buys are long since gone. Used litronics are often for sale on Ebay and 6speedonline, with a typical price range of $800 - $1000+. When buying used, the lights usually do not come with the (optional) litronic control module.

Many of us simply pull out the halogens and slide in litronics. They work fine as a direct swap. One feature you lose without the Porsche control module is xenon pivot on high beams. For a full installation including the control module, the Pelican Parts reference is a good one. Porsche also has a retrofit technical bulletin which you can find on renntech.
