Hey Bitt,
Scott (svferris) posted earlier about this product
LED display Caller Id device.

Which is if I undetstand your original request exactly what you want/posted about originally.

Its a LED display Caller Id device which is 10 inches wide and 3.5 inches high, and can be read from 20 feet away and doesn't use your TV as a display device.

It seems to do what most caller id devices do and perhaps a little more.
Its totally AC powered [well it would have to be to power those LED displays].

Only complaint I have - it has a RED LED display - I hate RED LED displays but thats my preference.

At $USD99 each its a little pricey but it will do a decent enough job.
