I had actually thought about a device like this before... I figured somebody
must have come up with one somewhere along the line but I never actually
looked for one 'til now.
I have a fair number of cassettes that I never replaced with CDs and I just
figured that I would patch my component cassette deck into the sound card
when I got around to that project- It's a high-end deck, which should
suffice, and I don't really have enough tapes to justify the $140 bucks for
this thing, but it might be worth it to someone that has a very large
library:

Getting the files onto an SD card would be pretty straightforward from
there.
