I would definitely consider the dealerships reputation...as far as brands--Jungheinrich is the world's number one brand when it comes to narrow aisle. Long run times, innovations and quality have gotten them there...I am also partial to Nissan electric sitdowns--they offer a fully AC lift and have an excellent reputation for good service and longevity...Nissan's LP/gas lifts are top of the line as well. Neither Jung or Nissan would be the cheapest upfront--but in the long run they would be money savers!! There are other good lifts out there that would do the job...again, key in on the dealership--get some references of how they have taken care of other customers...
