Show HN: Weekend project - a Magic: the Gathering historical pricing tool

This site came out of a some code I wrote to automate the pricing (and selling) of some cards on eBay. It turns out that the demand for historical information is greater than the demand for my cards :)

It's purely a side project for now but it's running along nicely at 1 million searches a month and is making enough on the side to pay for hosting and the occasional contract developer to help out.
