It rather depends on what your requirements are for a "good" scanner, but since the introduction of the Advanced Quality Scan in Nero CD-DVD Speed 22.214.171.124 I think that the BenQ DVD writers (1655, 1650, 1640, 1620) are now among the most useful CD scanners along with Plextor drives. (Not counting commercial scanning equipment).
You should know that e.g. BenQ DVD writers are far more picky than LiteOn CD-RW drives when it comes to scanning CDs, but IMO that's a good thing because LiteOn CD-RW drives are so good readers that you won't necessarily discover even major flaws on a CD.
Unlike other scanning drives, the BenQ DVD writers can report all the six different Exy errors in an Advanced Disc Quality Scan, whereas most other drives usually report only C1=BLER=E11+E21+E31 and C2=E32.
Plextor drives (except rebadges) report C1=BLER=E11+E21+E31 and C2=E22 and CU=E32 in PlexTools and PxScan/PxView.
LiteOn DVD writers are not very useful for CD scanning because they only report C1=E31 and C2=E32, so almost any disc looks really good in a scan.
So don't compare scans made in different drives directly against each other, unless you know that they report errors in the same way and that they are comparable readers.
