When considering a passenger elevator for your home, you probably will have done extensive research due to the high cost involved. And indeed, prices range widely depending on the manufacturer. Apart for the extensive research that you have already done, you must also know your own needs in order to match you with the right one for you.
Firstly you need to ask yourself is the type of stairs you have. Chair lift for stairs differs based on the type of stairs you own, namely indoors, outdoors, straight or curved. Obviously, the more complicated the stairs, the more expensive is the installation. Take for instance, straight flight of stairs for a wheelchair stair lift merely cost about 5,000 dollars as compared to a curved one which could set you back by 15,000 dollars.
There are four types of drive system which chair lift for stairs are available in, namely the rack and pinion, chain, cable and screw driven models. Amongst them, the rack ad pinion drivers are the most popular due to their affordability. Made for light duty, they suffice for almost all single person stair lifts. You might also wish to consider the type of materials used. Take for instance, the most reliable railings are often made of aluminum and steel.
And you do have a choice with the power used for running it. If you live in an area where power outages are frequent occurrences, a battery operated system would be more suitable in order to avoid being stranded in the middle of the stairs. For more in depth understanding of the various models, you are well advised to check out the relevant manufacturer sales agents, manuals and guides before you make up your mind on the model of your choice.
For aesthetics, you might wish to check if the gear racks are fitted within the system. For example, you might not wish to have unsightly gear racks fully exposed. There are models which alternatively do better in the aspect of aesthetics with the gear racks hidden away from sight, with more appealing designs and comfort.
Hence, there is no one best model of passenger elevator, but only the most suitable one based on your needs. Make the effort to research thoroughly and ask yourself what your actual needs are, before signing on the dotted line. You do not want to regret on a bad decision, especially with such a hefty price tag involved.
