mommyd, I agree with Colleen that if you can share more about your son's hearing loss, it would be helpful. Choosing a hearing aid depends on the severity of his loss. Manufacturers do not put a MSRP (manufacturers suggested retail price), at least that are known to the end users, on their products so prices can fluctuate. You may also find a cheaper device, but it may lack some desirable features (a telecoil, or Bluetooth connectivity comes to mind). There's also the cost for "bundling" of service. Make sure you know if a programming change is needed, if there will be a cost and for how long this option is available. There are different levels of professionals so that will factor in to a price. I would recommend finding out if there is a local chapter of HLAA, Hands & Voices, or AG Bell near you. You'll get a good feel of which hearing care providers are in your area and how they rate. You'll also gain some new friends that share hearing loss as their common bond.
