Yepp the 306 will be ok for airing tires and little jobs but not near what the 325 was. It's only good for 100lbs pressure and it won't have a very big tank with a 110V motor @under 2 HP. If you want any bang for your buck stick with a 325. I wouldn't do it. If it runs great resell it. People can't buy that good of an air pump for that price..
