Snap-On has announced that it will no longer support software updates for the MT2500 scanner.
This includes programmable black cartridges and standard red cartridges. I just read an announcement on the Snap-On website news about it.

This is the link to the .pdf that explains this in detail.

It basically says that update 9.2 will be the last update and that service for the black cartridges will be available until 2011.

Just something to keep in mind when bidding on the MT2500.
