As you want to run the script interactionless, you have to know the remotedir/filename, so it would be pointless to check its existence first - it's there or not. Why not get it and check success/failure?
Try
Code:
sftp  ${remoteuser}@${host} <<EOF 2>&1 >/dev/null | awk 'NR>1 {exit 1}'
get ${remotedir}/${filename}
EOF
echo $?

The awk piece will make sure the right exit code will be issued.

EDIT: The sftp ":" form will even simplify that:
Code:
sftp ${remoteuser}@${host}:${remotedir}/${filename} && echo "found" || echo "missing"
