Just my two cents but look for a central air conditioning fan from a AC installer. The fan unit usually slides right out of the housing and you can use a piece of plywood to build a mount out of one of your basement windows. It will draw so much air there is little chance of the cigar smell going up the stairs from the basement. Open a window at the opposite end of the basement to let fresh air in. Don't buy a new fan, salvage an old one save some big bucks.
