VueScan 8.6.11
Listed by TidBITS Talk members two years running as a top productivity software pick in our annual TidBITS Gift Guide (see “TidBITS Gift Guide 2009,” 7 December 2009, and “TidBITS Gift Guide 2008,” 8 December 2008), Hamrick Software’s scanning utility VueScan has been recently updated. The latest version addresses a compatibility issue with certain Dell all-in-one printers, a connectivity issue with the Photosmart D5400 printer, a failure of the skew box to update properly, and an interface problem with the multi-crop box. ($39.95 new, free update, 9.1 MB)

On a more serious note: I own it and love it, just note that "free update" is actually Free Updates for Life, even including full point upgrades.
