Hey guys, my dad has a hearing problem. Since I'm going back to nepal this summer, I'm planning to buy a hearing device for him. But I'm confused right now where to look for it. I've heard that those things are real expensive. Can any body give me any info. regarding therse things, where can I buy it or what kind of product is effective? any suggestion is welcome. Since my budget is really tight, I'm looking something that would not exceed more than $500.

Thanx in advance.
