Aquisition loan options that do NOT require a personal guarrantee?

It is my understanding that SBA 7a loans typically want the borrow to provide a personal guarantee and put a lien on a primary residence. What loan options exist where one could borrow for an acquisition and NOT have to provide a personal guarantee or have your home attached? Are there certain loan options besides the SBA loans that could be considered? How do the loan options vary based on different industries? I would think that a business with assets like real estate and equipment might have additional financing options as compared to some service-based businesses. Thanks!
