I have one of those cheap HF cabinets that worked fair at best. I rebuilt the head with eastwood http://www.eastwoodco.com/shopping/product/detailmain.jsp?itemID=1326&itemType=PRODUCT&iMainCat=1310&iSubCat=1316&iProductID=1326 and it has has never worked so well and fast. The cabinet still leaks like crazy.
