Yes. I think that many new users might think along the same lines, especially since one can get just about anything on Ebay.
I got a sweet deal on some second hand HAs, and turned a small profit when I took advantage of the HA trade in offer
It was a good experience, I got to fiddle with dials and learn how to put in batteries with none of the apprehension of cluelessly ditzing around with a set of HAs that cost thousands.
But at the same time I was reading and researching and realized that HAs are complex and they have to be programmed just for the person wearing them.
If you find an audi that would do it for you, it might be OK. But audis are professionals like doctors and so on and you are paying for knowledge and experience, not just the small amount of time it takes to program, so by the time you are done it is possible that you might spend near what you would have spent on a new set from AH.
My hearing is precious and I saw what a good rep AH has. Their prices are reasonable, their service is excellent. So to me, getting a quality set of HAs that was made for me was worth the cost.
