I simply have not bought any games at market value for the last five years unless they were under 1K. When the going rate for a Swords of Fury or a Mousin' Around is over 2K, I simply just can't justify it. I have less invested in my entire collection than some people have in a single LE machine and that fact alone blows my mind.
Instead, I've just been waiting patiently for good deals to pop up and then try to trade for the games I want. It's more exciting that way at least!
