Paragon Backup & Recovery
Paragon Backup & Recovery 2011 (Advanced) Free has "Restore with Shrink" to restore a backup image into a smaller disk, taking into account only the amount of actual data of the image. That means that the amount of used space on the HDD be smaller than the full size of the SSD, with a few gigabytes still left free as a security measure.
Another solution to the size problem is to rather use a copying tool such as HoboCopy to copy from the HDD to the SSD. It uses shadow-copy and so can also copy files that are in use.
Acronis True Image
For straight disk-cloning, Acronis True Image Home ($49.99) is another good possibility. The target disk can also be of any size with the same considerations as above.
Other free cloning tools are:
DriveImage XML

Runs runs from within Windows and can backup logical drives and partitions to image files, but doesn't have a boot CD (you need to create a BartPE Boot CD).
Many people rave about it.
EASEUS Disk Copy

is is a great alternative if you don't want to go for a 'hot' backup that runs from within Windows. Good review at lifehacker and on a par with DriveImage XML. A boot CD is supplied.
