I have absolutely no idea of the state of play of eye-based input devices, but I wouldn't expect an entire eye-input keyboard system to be anywhere near as cheap as $1K, but rather a figure 20-100x that.

They're currently in the $1,000-$3,000 range.

We (The Eye Tribe folks) sold one at 99$ years ago. 1k-3k is mostly lack of competition I believe.
