cheapest welder for aluminum?

i need to weld 3/16" sheet aluminum for a boat i'm making and want to do it at the cheapest cost. this welder (http://www.harborfreight.com/90-amp-flux-wire-welder-68887.html) says it won't do aluminum (and i'm not sure 90 amps would be enough anyway). Is that true? What if i bought the 180 amp model? Any suggestions for other welders?
