Hi Ed,
MTS Aviation Models, a hobby shop in Ohio, had both kits in their inventory as of last weekend. The Revell DC-10s were listed at $40 not including shipping. Their website is MTSAviationmodels.com.

Discovering Clint Groves and his ATP/Airliners America catalog in the late '70s made me realize I wasn't the only hobbyist with an interest in building airliner models. Beginning with Aurora kits and now enjoying the latest offerings from Revell Germany and Zvezda in 1/144 scale, it's been a fun ride.
