Replying to Adapter Help!

So I have a Quantaray 70-300mm F/4.0-5.6 Zoom Lens (crappy lense that I got for free) for a Minolta AF mount. My problem is that I have canon t2i and the lenses obviously are not compatible with my camera. I've looked around at some adapters but I'm confused on which one to buy because it seems like there are many different adapters for many different specific mounts. If anyone could point me in the right direction it would be much appraicted. Thanks
