Wife thinks we need a Stairlift if we are going to stay in our home.
We have started the process. We have time!
So far we have interviewed 2 Sellers… Nice folks but knowledge and Selling Style questionable.
I had viewed several Youtube Videos… including one on installation… not that I would even consider installing one myself… but it provided a lot of information on How they work, Safety Features etc. Frankly, I felt I knew more than the Rep from those Videos.
I had assembled a list of Questions… for most of which he had to call his Manager… did not inspire confidence. I asked if a Techie would do a final assessment before installation. He said he would do it. 
Starting price for a straight stairs was $8,000. Double that for a curved stairs.
The price dropped to about $4000 if I signed today. I said I was not buying a Time Share… he understood. Options like Power Swivel chair and “Bottom Rail Auto Foldup” added 2000 and no deal on them.
I told the second one he was not the first nor the last. I viewed this similar to buying a car. Gather info, decide on the Dealer, do a test drive… and if they were chosen, I would expect the today price. Funny, I got no resistance on that.
Be aware, there is far more and better info on YouTube than the Glossy Brochure provided.
I was amazed how many are in this Business. Unlike car videos, I found no side by side comparisons you need to watch them and take notes.
A Friend who has one would be helpful especially when it comes to Service after the Sale.
