Helping my Dad

Hello all,

I am brand new to this forum and the hearing aid scene.

My father has had In-The-Ear (ITE) aids in the past and recently had new audio tests done. Based on the tests, the guy he saw recommended a few of his new Behind-The-Ear (BTE) products at what I imagine may be an obnoxious mark-up. My dad liked the Audibel Virtue 12 (I think the same as Starkey Destiny 1200). However, I have heard mixed reviews on that line of aids - not to mention the guy wanted $6500 a pair!

My questions to you all:

Any advice on how I can best help my dad in this proces?
Any experiences with this specific product?
Any products out there with the same or better functionality for my dad?
Can one shop online for aids? If so, where are some good/reputable sites?
Since he’s looking at Behind-The-Ear, does he need a proper fit by a doc?
What about Hearing Planet or Genesis? Are they to be avoided?
Where can my dad go with his tests to try out more aids for himself?
What would you all do in my situation?

Thank you all in advance for any input you may share!

It will mean a great deal to me and my dad,
