We had Racedeck in the last house, looked great but not cheap, I know theirs some other similar ones that are a lot less...think Sears has their own brand also? Pry just as good. The only thing is, if you live in very cold climates like where you are and then it gets warmer in the summer, the tiles can contract and expand eventually causing gaps and not fitting correctly.
Epoxy with Speckle looks good but so hard to do by yourself, better off having a professional. Almost every single garage I've seen where somebody bought a kit to do themselves, couple years later they start having issues with fading and cracking etc.
