You have to get a drill for a left hand rotation. In other words buy any Jiffy ice drill assembly for their power ice auger heads. Jiffy's Standard, D'Icer, XT and Stealth/STX ice drill assemblies will all fit. The 2hp powerhead works best with 6"-8" drills but you can go a little bigger to a 9" if you want. I have a 6" and a 9" for my Jiffy 2hp but the 9" is pushing it, better to stay in the 6"-8" size range. You can get the drill straight from Jiffy or you can buy it through several online sites. You can pick up deals on ebay and craigslist sometimes also. The online sites should be updating their sites and getting ice gear in stock within the next couple months.
