Marklin mfx booster 60172.
Have you order the 60172 for more that 2 years? Marklin have info me that 60172 mfx booster will delivery from October 2008. :wink:

Marklin writes in the 6021 manual that ski lifters are not needed for the 6017. They write in the CS manual that ski lifters are needed - maybe they'll write something else in the 60172 manual or in their FAQ list. Ignoring the manual could void the warranry - no matter what Mr. Lorenz said; I'd prefer something written (that's just my precaution).
