The Koamtac KDC 200 scanner was the scanner of choice for many years in the book selling community. It offers quick connection, an LCD pairing screen and relatively fast charging(for the time). However the major complaint for this older scanner is the button not being very smooth. This becomes a huge problem once you're at a book sale scanning hundreds and thousands of times. Additionally, it's known for its "red dot" problem. This is when the scanner no longer scans, it simply gives you a laser beam light and rendered useless unless you service it.
