I have 2 hearing aids as supplied by the nhs:
Opticon Spirit Zest mini.
If you google the name, you'll find they are not cheap outside the nhs.
AFAIK they are as good as anything available privately.
Before getting sucked-in to going the "Hidden Hearing" route, ask yourself if you really don't want the people trying to speak to you, to know you're a bit Mutt 'n Geoff.
Personally, I find it helps when people can see the aids.
Whichever way you go, persevere with them - You'll find them very harsh at first, because you've got used to not hearing the sibilants & percussives (assuming that's the problem). I got used to mine in a few days, but I know others who struggle: You can always turn them down a bit.
