I agree with Shop Shark. Why not get a good sized compressor right from the start. Tractor Supply has a good slection of compressors. I bought one maybe fifteen yrs. ago from TSC with an eighty gallon tank and capasity of somthing like twelve CFM"s. This is large enough to do just about any knid of work you want and over the years will not depreicate like the small ones do. Buy once, spend the extra money and be happy.
