Here is the link to Sheldon Brown's site that has a short blurb on Grandis. Other good stuff here too-just go to the top and select the make of bike you are interested in. Originally published by Mike Kone in The Vintage Racing Bicycle Newsletter in the early 90s, but I don't know whether it was ever updated. Site says prices not updated since 1997.

GRANDIS: An Italian frame of the highest caliber. Not terribly well known. Branford Bike sold many of these in the U.S. during the early 80's. A classic Italian frame, very nice with S.R. components. Be wary, though, of examples on the small side - one frame owned by a friend was terribly designed - larger models aren't known to have similar maladies. S.R. equipped bike in guideline condition should be worth around $900.
