   With respect to the interface kit I do not know a lot. However, the
interface itself is trivial (a design of my own works fine for me and I
have made three more sets for friends -none of which has problems). A
design -it turned out that mine is similar to it- can also be found at the
September's issue of Popular Electronics. The hardware cost about $5. The
success of the design largely depends on the cassette recorder, and it 
usually takes one hour in order to find the volume and tone levels that
give the best results. In terms of time, it can be done in an evening,
it takes two to four hours (most of the time is spent drilling holes in
the box, stripping cables, etc, the actual connections of the electronics
take around half an hour).
   Another aspect is the tape that you use. I found -the hard way- that a
good tape is essential, so I use TDK SA-90 (this is not an advertisment, I
pay for my tapes), and usually I buy a 90 minute SA-90 and load it in the
shells of many bargain tapes (those 3 for $1), so the search time is
smaller.
   If you -or any other netter- are interested in my design, drop me a
line (my address follows) or send me some electronic mail and I will be
glad to send you a copy.
