From the looks of it, PC mag used a tester box that doesn't match most
noise found in real life. It isn't the S/N ratio that is wrong, it is the
KIND of noise they used that is wrong. Telebit modems do just GREAT with
most kinds of real-life noise, no matter how bad!

I'd go ahead and get the TB. You might try calling Telebit to ask if they
have experience with connections to Taiwan. If they don't, try getting
a guaranteed refund if the modem simply won't work. Then you won't be
stuck if for some reason the experiment fails. It never hurts to ask!
