Buffalo,
Yes, I've always worn Lucite hard earmolds, so I've become quite used to them. They've always felt comfortable to me -- more comfortable in fact than "Patriot" earmolds which are extremely painful to insert and remove -- not to mention the fact that they keep sliding out of my ears. Several months before I received my CI, I wanted to get a new earmold for my BTE CI speech processors, but unfortunately, I couldn't find a local audi who ordered Lucite earmolds. I ended up having to go to the audi who fitted me with my first pair of hearing aids back in 1985. Thank goodness she was available otherwise I don't know how I would have been able to receive new earmolds.
I know what you mean about trying to save money. Normally it costs $50/earmold, but my audi (the one who fitted me with my first pair of aids) was nice enough not to charge me. I'm thankful for that because I was living on a pretty limited income at the time.
