I'm not sure how that drive behaves as a scanner compared to the later models, because I don't have such a drive and I can't remeber seeing any direct comparisons of scans with this drive. So I really can't say.
I have seen posts indicating that the newer LiteOn CD-RW burners are not as good for writing quality as some of the older ones, so if I could get my hands on an older LTR-52246S I would buy it if the price was reasonable, but if you take a look at my sig you'll see I like to have lots of drives.
If you want to test the scanning behaviour of your drives, or drives you can borrow, you can do what I did - make your own test CD. There are instructions on how to do that on the Nero CD-DVD Speed site, but I did it in a simpler way.
Start with a CD with really good quality, such as a CD-R burned at an optimal speed on a good burner. This should be a CD that you don't need for any other purpose than testing. Then take a black permanent marker pen and write a line on part of the disc data side so that it goes from the center outwards. The line shouldn't be wider than 1-2mm (1mm = 0.04 inch) and should not go all the way in to where the data begins.
You can then use this test disc to compare how different scanning drives report C1/C2 errors on that disc. Such a disc will have C2 errors of the E22 kind and perhaps also E32 errors. Most scanning drives will report only E32 as C2 errors, while a few drives will report also E22.
