Dan...Unless you already have ics and scs that you feel you might be able to "live with", your only opther options, it seems, are to take a chance with buying based on what you've read or heard from others or making an effort to contact The Cable Company and have them send you something for audition. True, there is a charge for borrowing, which can be used as credit toward buying from them, but even if you don't, you might find yourself in a better situation money wise in contrast to buying from someone outright and finding that you don't like what you've bought. Good luck, in any event.
