I've not used one but there would seem to be cheaper ways of doing it. All you need is
1. Something to play the tapes on ;
2. A lead between that device and your PC ; and
3. Some suitable software.
For item 1 you could use a Sony (Cassette) Walkman or similar, as long as you keep the volume control set to a fairly low level. It would be better to buy a 'hi-fi separate' tape deck (cheaply from a charity shop), which has phono outputs.
